A user who has checked a finished state of the trial printing sets, when the finished state is in a desired state, the recording paper on which the trial printing is performed to the paper feed portion again and executes the repeat printing. Thereby, in a blank space excluding a print image which is printed with a first time trial printing, a scheduled quantity of a plurality of images are repeatedly printed. ## Claims ### Claim 1 An image forming apparatus, comprising: an image forming portion which forms an image of image data on recording paper; and a paper feed portion which feeds the recording paper to the image forming portion, the image forming apparatus being configured to carry out a repeat printing function which forms images by repeatedly arranging the image data on one sheet of the recording paper, and a trial printing function which, when forming a plurality of the images for one of the image data, forms only one image for the image data first, and subsequently, forms the image again in response to input of an image formation instruction, wherein the image forming portion enables execution of the trial printing function in a mode of executing the repeat printing function, and in forming the image by the trial printing function, forms only the one image on a part of the recording paper for the image data to be printed by means of repeat printing, and in response to input of an instruction to execute printing by the repeat printing function, feeds the recording paper on which the image is formed by the trial printing function again by the paper feed portion and forms a scheduled quantity of images by the repeat printing function in a blank space on the fed recording paper, and the trial printing function is repeated so as to form the image again after first forming the one image, and an indication is added to the one image formed by the trial printing function if the one image is not used to form the scheduled quantity of images by the repeat printing function. ### Claim 2 (depends on 1) The image forming apparatus as defined in claim 1, wherein the image forming portion enables repetitive execution of forming the image more than once by the trial printing function, and when forming the image by the trial printing function, forms a next image by the trial printing function at a position of a blank on the recording paper excluding a position of the image formed by the trial printing function in the past. ### Claim 3 (depends on 2) The image forming apparatus as defined in claim 2, wherein the image forming portion forms the scheduled quantity of images by the repeat printing function at the position of the blank on the recording paper excluding a position of the image formed by the trial printing function, when forming the scheduled quantity of images by the repeat printing function after forming the image is repeated more than once by the trial printing function. ### Claim 4 (depends on 2) The image forming apparatus as defined in claim 2, wherein the image forming portion attaches, to the image excluding the image of conditions used for forming images by the repeat printing function among the plurality of images formed by the trial printing function, the indication for clearly showing that the image is not used for the repeat printing, when forming the scheduled quantity of images by the repeat printing function after forming the image is repeated more than once by the trial printing function. ### Claim 5 (depends on 2) The image forming apparatus as defined in claim 2, wherein the image forming portion stores print conditions of the plurality of images formed by the trial printing function performed more than once, allows a user to select an image to be used in forming the image by the repeat printing function among the plurality of images, and forms the scheduled quantity of images by the repeat printing function with use of the print conditions corresponding to the selected image. ### Claim 6 (depends on 1, 2, 3, 4, 5) The image forming apparatus as defined in any one of claims 1 to 5, wherein the image forming portion attaches, to a predetermined position of the recording paper, an indication showing a setting direction of the recording paper to the paper feed portion again, when forming the image by the trial printing function.
