Abstract
In order to provide an image forming system characterized by compact configuration, high speed printing, high picture quality recording and excellent maintainability without image misregistration, an image forming system is provided, wherein multiple photoconductors are arranged along one of the surfaces of the intermediate transfer belt which is elongated in the longitudinal direction, and a fusing device is located on the other surface, with the photoconductors being integrated in one unit.
Claims13
An image forming system comprising:
- multiple photoconductors arranged in a line and combined in one body of said image forming system;
- multiple development devices and multiple exposure devices arranged on one side of said line of said multiple photoconductors;
- an intermediate transfer device arranged on the other side of said line of said multiple photoconductors;
- and
- a form cassette arranged below said line of said multiple photoconductors;
