Image forming apparatus and driving method for driving image forming apparatus
An image forming apparatus includes a latent image bearer, a charging roller, a first cleaner, a second cleaner, and a rotation controller. The latent image bearer bears a latent image on a surface thereof. The charging roller charges the latent image bearer. The first cleaner cleans the surface of the latent image bearer. The second cleaner cleans a surface of the charging roller. The rotation controller controls the latent image bearer to execute a set of backward rotation and first forward rotation at least once during a non-image formation time period, and either temporarily stop and start second forward rotation or continuously execute the second forward rotation by a rotation distance corresponding to at least one rotation of the charging roller.
