Abstract
An image forming apparatus includes an image forming unit configured to form a toner image on a sheet, a fixing unit configured to fix the toner image on the sheet, a double-sided conveyance path along which the sheet is conveyed for double-sided printing, and a control unit configured to control conveyance of the sheet, allowing the sheet to be stopped at a first standby position which is more downstream than the fixing unit in a sheet conveyance direction on the double-sided conveyance path and a second standby position which is more downstream than the first standby position, and changing stopping time for which the sheet is stopped at the first standby position and stopping time for which the sheet is stopped at the second standby position according to a material of the sheet.
Claims22
An image forming apparatus comprising:
- an image forming unit configured to form a toner image on a sheet;
- a fixing unit configured to fix the toner image formed by the image forming unit on the sheet;
- a double-sided conveyance path along which the sheet is conveyed to form, after a toner image is fixed to one face of the sheet by the fixing unit, a toner image on the other face of the sheet;
- and
- a control unit configured to control conveyance of the sheet, allowing the sheet to be stopped at a first standby position which is more downstream than the fixing unit in a sheet conveyance direction on the double-sided conveyance path and at a second standby position which is more downstream than the first standby position, and changing stopping time for which the sheet is stopped at the first standby position and stopping time for which the sheet is stopped at the second standby position according to a material of the sheet.
An image forming apparatus comprising:
- an image forming unit configured to form a toner image on a sheet;
- a fixing unit configured to fix the toner image formed by the image forming unit on the sheet;
- a double-sided conveyance path along which the sheet is conveyed to form, after a toner image is fixed to one face of the sheet by the fixing unit, a toner image on the other face of the sheet,
- a conveying unit configured to convey the sheet along the double-sided conveyance path,
- wherein the double-sided conveyance path includes a first standby position where a sheet is stoppable, and a second standby position downstream to the first standby position with respect to a sheet conveyance direction;
- and
- a control unit configured to control the conveying unit so that a sheet conveyed on the double-sided conveyance path is stopped at the second standby position, and the sheet is conveyed from the second standby position to the image forming unit at a predetermined timing,
- wherein the control unit controls the conveying unit so that a sheet is stopped at the second standby position without stopping at the first standby position in a case where a first-type sheet is conveyed on the double-sided conveyance path, and so that a sheet is stopped at both the first standby position and the second standby position in a case where a second-type sheet is conveyed on the double-sided conveyance path.
An image forming apparatus comprising:
- an image forming unit configured to form a toner image on a sheet;
- a fixing unit configured to fix the toner image formed by the image forming unit on the sheet;
- a double-sided conveyance path along which the sheet is conveyed to form, after a toner image is fixed to one face of the sheet by the fixing unit, a toner image on the other face of the sheet;
- a conveying unit configured to convey the sheet along the double-sided conveyance path,
- wherein the double-sided conveyance path includes a standby position at which the sheet stops;
- and
- a control unit configured to control the conveying unit so that the sheet conveyed on the double-sided conveyance path is stopped at the standby position, and the sheet is conveyed from the standby position to the image forming unit at a predetermined timing,
- wherein the control unit controls the conveying unit so that a time period required to convey the sheet from the fixing unit to the standby position is changed according to material property of the sheet.
