Abstract

A developing device is refilled with an initial developer while the developing device and a photoreceptor are maintained within an image forming apparatus in the same state as in an image forming process. When refilling the developing device, a control unit of the image forming apparatus first drives a stirring feed member (screw) to feed the initial developer into the developing device, and then drives a developer carrier (developing roller) and a latent image carrier (photoreceptor) to supply the developer onto the developer carrier.
