Abstract

Official abstract text for this publication.

An image forming apparatus includes a detachably mountable developing device including a developer container, a developer carrying member, a feeding member, provided in contact with the developer carrying member, for supplying the developer to the developer carrying member, and a developer regulator; and a voltage device capable of applying to the developer carrying member and the developer regulator respective voltages different from each other. The image forming apparatus carries out, when a fresh developing device is mounted, an initial operation in which the developer carrying member is rotated. In the initial operation, the voltage device applies, to at least one of the developer carrying member and the developer regulator, a voltage for the initial operation which is different from the voltage for normal image forming operation, so as to urge a material applied to the developer carrying member in the fresh developing device toward the developer regulator from the developer carrying member.
