摘要：
The invention provides a color image forming apparatus capable of forming a mono-color image and a multi-color image on a rotatable photoreceptor having a given circumferential length. In the apparatus, there are provided a selection switch for selecting either a mono-color mode for forming a mono-color image or a multi-color mode for forming a multi-color image, and a control circuit responsible to a selection signal of the selection switch so that, when the multi-color made is selected, an image size of a multi-color image is restricted within a maximum size corresponding to the circumferential length of the photoreceptor.
