摘要： A color electrophotographic apparatus using a plurality of image forming units (31Bk,31Y,31M,31C). The entire image forming unit group moves by rotation, and a toner image is transferred on an intermediate transfer belt (49) at an image forming position. The intermediate transfer belt (49) is variable in speed, and while the image forming unit group is moving, it is stopped or runs at low speed. The hopper in the image forming unit (31Bk,31Y,31M,31C) is divided into two sections. The toner is supplied to the image forming position, and when the toner remainder sensor detects no remaining toner, the image forming unit group rotates by one revolution or more, and then the toner remainder is detected again to judge presence or absence of toner remainder. At this time, the toner in the toner hopper is agitated by the agitating member. After rotary move of the image forming unit group, each image forming unit is initialized sequentially. The side walls of the signal light optical path are composed of image forming units, and the color of the side walls is black. The gap between two adjacent signal forming units is 20 mm or less. One erase lamp of the photosensitive member is provided near the image forming position. During rotary motion of the image forming unit group, it is controlled so as not to disturb the toner image on the intermediate transfer belt (49).
