If a first print medium is a print medium to be used for single-sided printing and a re-conveyed print medium is located within a predetermined distance from a region where the first print medium is located, an interval between the region where the first print medium is located and a region where a second print medium is located is controlled to be a first interval. If the first print medium is a print medium to be used for single-sided printing and a re-conveyed print medium is not located within the predetermined distance from the region where the first print medium is located, the interval between the region where the first print medium is located and the region where the second print medium is located is controlled to be a second interval shorter than the first interval. ## Claims ### Claim 1 A conveyance apparatus comprising: (A) a conveyance unit configured to convey, using a conveyance path, a print medium to an image forming component configured to form an image on the print medium; (B) a supply unit configured to supply the print medium to the conveyance path; (C) a re-conveyance unit configured to re-convey, to the image forming component, the print medium, on which the image is formed by the image forming component, to perform double-sided printing; and (D) a control unit configured: (a) to control, if a first print medium among supply target print media supplied by the supply unit is a print medium to be used for single-sided printing, and the print medium re-conveyed by the re-conveyance unit is located within a predetermined distance from a region where the first print medium is located on the conveyance path, the supply unit so that an interval between the region where the first print medium is located on the conveyance path and a region where a second print medium supplied to the conveyance path next to the first print medium is located on the conveyance path becomes a first interval; and (b) to control, if the first print medium is a print medium to be used for single-sided printing and the print medium re-conveyed by the re-conveyance unit is not located within the predetermined distance from the region where the first print medium is located on the conveyance path, the supply unit so that the interval between the region where the first print medium is located on the conveyance path and the region where the second print medium is located on the conveyance path becomes a second interval shorter than the first interval. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein, if the first print medium is a print medium to be used for double-sided printing, the control unit controls the supply unit so that an interval between a position of the first print medium on the conveyance path and a position of the second print medium on the conveyance path becomes the first interval. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein, if the first print medium is a print medium to be used for single-sided printing, and a third print medium that is a predetermined number of pages after a page number of the first print medium is a print medium to be used for double-sided printing, the control unit controls the supply unit to supply the third print medium prior to the first print medium. ### Claim 4 (depends on 3) The apparatus according to claim 3, wherein the control unit controls the supply unit so that an interval between the region where the first print medium is located on the conveyance path and a region where the third print medium is located on the conveyance path becomes the second interval. ### Claim 5 (depends on 3) The apparatus according to claim 3, wherein, when the predetermined number of pages is M and the number of print media which can be arranged on the conveyance path is N, M=largest integer not greater than N/2. ### Claim 6 (depends on 3) The apparatus according to claim 3, wherein, after a plurality of print media to be used for double-sided printing are supplied subsequently to the third print medium, the control unit controls the supply unit to supply the first print medium to the conveyance path. ### Claim 7 (depends on 6) The apparatus according to claim 6, wherein, after the plurality of print media to be used for double-sided printing are supplied subsequently to the print medium to be used for single-sided printing, the control unit controls the supply unit to supply a number P of print media to be used for single-sided printing to the conveyance path, and, when the number of print media that can be arranged on the conveyance path is N, P=(larger integer not greater than N/2). ### Claim 8 (depends on 6) The apparatus according to claim 6, wherein, when the predetermined number is M and the number of print media that can be arranged on the conveyance path is N, M=(larger integer not greater than N/2)×2. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the first interval is a length corresponding to a size of one print medium. ### Claim 10 (depends on 1) The apparatus according to claim 1, further comprising: a reception unit configured to receive a job for forming the image on the print medium by the image forming component, wherein, if the reception unit receives the job, the supply unit supplies the print medium to the conveyance path. ### Claim 11 A control method for controlling a conveyance apparatus, the control method comprising: conveying, using a conveyance path, a print medium to an image forming component configured to form an image on the print medium; supplying the print medium to the conveyance path; re-conveying, to the image forming component, the print medium, on which the image is formed by the image forming component, to perform double-sided printing; and controlling, if a first print medium among supply target print media is a print medium to be used for single-sided printing and the re-conveyed print medium is located within a predetermined distance from a region where the first print medium is located on the conveyance path, supply of the print medium to the conveyance path so that an interval between the region where the first print medium is located on the conveyance path and a region where a second print medium supplied to the conveyance path next to the first print medium is located on the conveyance path becomes a first interval, and controlling, if the first print medium is a print medium to be used for single-sided printing and the re-conveyed print medium is not located within the predetermined distance from the region where the first print medium is located on the conveyance path, supply of the print medium to the conveyance path so that the interval between the region where the first print medium is located on the conveyance path and the region where the second print medium is located on the conveyance path becomes a second interval shorter than the first interval. ### Claim 12 A non-transitory computer-readable medium storing a program for causing a conveyance apparatus to execute: conveying, using a conveyance path, a print medium to an image forming component configured to form an image on the print medium; supplying the print medium to the conveyance path; re-conveying, to the image forming component, the print medium, on which the image is formed by the image forming component, to perform double-sided printing; and controlling, if a first print medium among supply target print media is a print medium to be used for single-sided printing and the re-conveyed print medium is located within a predetermined distance from a region where the first print medium is located on the conveyance path, supply of the print medium to the conveyance path so that an interval between the region where the first print medium is located on the conveyance path and a region where a second print medium supplied to the conveyance path next to the first print medium is located on the conveyance path becomes a first interval, and controlling, if the first print medium is a print medium to be used for single-sided printing and the re-conveyed print medium is not located within the predetermined distance from the region where the first print medium is located on the conveyance path, supply of the print medium to the conveyance path so that the interval between the region where the first print medium is located on the conveyance path and the region where the second print medium is located on the conveyance path becomes a second interval shorter than the first interval.
