Abstract
An electrophotographic printing apparatus is provided. This printing apparatus includes a photosensitive medium designed to form thereon an electrostatic latent image, a developing roller designed to tone the electrostatic latent image with a toner to form a toner image on the photosensitive medium, a driving mechanism for driving the developing roller for rotation, a transport mechanism for moving the developing roller into engagement and disengagement with and from the photosensitive medium for the formation of the toner image thereon, and a control unit adapted to control the driving mechanism to rotate the developing roller immediately before the developing roller is brought by the transport mechanism into engagement with the photosensitive medium, and controls the driving mechanism to stop the developing roller from rotating immediately after the developing roller is moved by the transport mechanism away from the photosensitive medium.
