Abstract
Official abstract text for this publication.
An image forming apparatus includes an image bearer, a developing device, a motor, and circuitry. The developing device includes a screw and a developing roller. The screw stirs and conveys a developer. The developing roller bears the developer stirred and conveyed by the screw, brings the developer into contact with the image bearer, and develops an electrostatic latent image on the image bearer. The motor drives the developing device at multiple process speeds. The circuitry is configured to cause the motor to drive the screw and the developing roller before the developing roller starts developing the electrostatic latent image on the image bearer and adjust a drive time of the motor based on a process speed in a previous printing and a process speed in a next printing.
