IMAGE FORMATION DEVICE, COMPUTER PROGRAM, IMAGE FORMATION SYSTEM, AND IMAGE FORMATION METHOD

摘要

[PROBLEMS] To realize a user-friendly image formation system. [MEANS FOR SOLVING PROBLEMS] An image formation device can be used as a color image formation device for forming a color image and as a monochromatic image formation device for forming a monochromatic image. In the image formation device, one of the development units mounted is moved to a mounting/detaching position so that the development unit can be replaced. When such an event has occurred that development cannot be performed by a predetermined development unit, the timing for moving the predetermined development unit to the mounting/detaching position is different between the color image formation mode and the monochromatic image formation mode.
