Abstract
When a photoreceptor unit and a developing unit are combined with each other, the photoreceptor does not come into direct contact with the developing unit. Accordingly, it is possible to prevent generation of scratches on the surface of photoreceptor, and lowering of electrostatic sensitivity due to scratches may be prevented. As a result, an excellent image will be formed. It improves the efficiency in the manufacture of image forming apparatus. A method of manufacturing an image forming apparatus of the present invention includes a process of applying a toner to the surface of developing roller and a process of making the developing roller with the toner applied thereto come into contact with the photoreceptor to combine the developing unit and the photoreceptor unit with each other. Preferably, the manufacturing method further includes a process of performing functional tests of a finished image forming apparatus.
