Abstract
An image forming apparatus includes a latent image bearer having a shaft to rotate in a normal direction for image formation and a reverse direction, a charging device, a latent image forming device, a developing device including a developer bearer having a shaft, a driving source, a drive transmission device to transmit a driving force from the driving source to the shaft of the latent image bearer and the shaft of the developer bearer. The developer bearer rotates in a predetermined direction during image formation and transports developer including toner to a developing range facing the latent image bearer, thereby developing the latent image on the latent image bearer. The drive transmission device is configured to inhibit transmission of the driving force to the shaft of the developer bearer when the latent image bearer rotates in the reverse direction.
