ABSTRACT:
Three mounting portions are provided along a direction of rotation of a photoreceptor, on the downstream side of an eraser and a corona charger. A first developing unit, an outline unit and a second developing unit are mounted in this order from the upstream side. The units can be attached to and detached from the mounting portions. When an outline mode is designated, the color of the developing unit mounted on the downstream side of the outline unit is displayed on a display portion. When one color is designated out of the displayed colors, the developing unit of that color is operated to carry out a copying operation in the outline mode. When the color is not designated, the copying operation is carried out by a developing unit having a prescribed color mounted on the downstream side of the outline unit.
