Abstract
Engaging shafts and are protruded coaxially with a drive roller and driven rollers around which a photosensitive belt is rotatably wrapped inside a photosensitive belt casing, and are positioned in engagement with an engaging groove in a side plate of a frame and with a curved surface formed in a guide rail that guides the photosensitive belt casing. This enables the photosensitive belt to be precisely opposed to an intermediate transfer drum and to developing devices, and to be easily attached to and positioned in the apparatus or detached therefrom.
