Image forming device
Document Type and Number:
Japanese Patent JP6323745
Kind Code:
B2
Abstract:
An image forming apparatus includes multiple image forming units each accommodating an image bearer and a developer bearer to develop a latent image formed on the image bearer. Each of the image forming units other than a prescribed image forming unit runs in an ordinary reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in an opposite direction during a non-image formation time period. The prescribed image forming unit runs in a special reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in the opposite direction during the non-image formation time period based on a differentiated one of a rotation time period, a start timing, a rotational speed, and a frequency of operation from those of the other image forming units, or does not run in the special reverse rotation mode.
