とを特徴とするカラー画像形成装置。 Color-separated light images are formed on a plurality of belt photoreceptors, and visualized with color toner corresponding to each light image.
In a color image forming apparatus of the type in which the color toner images are sequentially transferred from a belt photoreceptor to a transfer paper fed onto a transfer belt, the drive roller of each belt photoreceptor is constructed of a core metal and a rubber layer with the same dimensions. A color image forming apparatus characterized in that the thickness of the rubber layer of the drive roller provided in the area where the ambient temperature is high is made thinner than the thickness of the surrounding area.
