Filed: 2020-05-12
Abstract: To solve the problem in which: conventionally, an image forming apparatus of an electrophotographic system is known to transfer a toner image for supply to an area on an intermediate transfer body, the area being between the sheets; it is known that a service person adds a grating pattern to a scan image when performing printing; however, when an inexpensive image processing chip is used, the pattern cannot be changed within the image, and thus it is difficult to add the toner image for supply and the grating pattern at the same time.SOLUTION: An image processing chip is used for a scan image, the image processing chip capable of setting a first color to a patch image and setting a second color to a service grating. Both the patch image and the service grating can thus be added to an image based on the scan image without using a high-performance chip as the image processing chip.SELECTED DRAWING: Figure 7
