Abstract
An image forming apparatus executes an image formation process through which a developer image is formed on an image carrier by developing an electrostatic latent image while rotating a developer carrier in a forward direction, a voltage controller controls development and regulating voltages after the image formation process such that a magnitude relationship between the development regulating voltages becomes inverted from that during the image formation process, and after finishing the image formation process, in a state where the magnitude relationship between the development and regulating voltages is inverted from that during the image formation, the drive controller rotates the developer carrier in the forward direction for a prescribed period, and afterwards rotates the developer carrier in a reverse direction for another prescribed period.
