摘要:
As the speed of a photoconductor drum 1a can be independently varied by providing a rotational speed adjustment mechanism to the photoconductor drum 1a, an inclined angle in a diagonal direction can be varied and as a result, misregistration can be adjusted. Also, exposure device with the inclination of a scanning line with the photoconductor drum 1a provided and control over correcting the inclination of the scanning line on the photoconductor drum 1a is executed by control over varying the peripheral speed of the photoconductor drum 1a. Hereby, a multiple image formation device wherein the configuration of color misregistration correction device is simplified is provided as an image formation device used for the output device of a computer and others.

A motor pulley for driving a photosensitive drum and a motor gear for driving a developing roller are fixed to a rotating shaft of a motor. The developing roller is provided with a developing roller driving gear which engages with the motor gear, and the photosensitive roller is provided with a photoreceptor driving pulley, to which a driving force from the motor pulley is transmitted.

An image forming apparatus is provided which includes a recording sheet ejection outlet, an ejected recording sheet tray, and a manual recording sheet feed inlet. The recording sheet ejection outlet is formed in an end portion of an upper surface of a casing. The ejected recording sheet tray is provided adjacent the recording sheet ejection outlet. The manual recording sheet feed inlet is formed in the other end portion of the upper surface of the casing opposite the recording sheet ejection outlet across the ejected recording sheet tray so as to utilize the ejected recording sheet tray as a recording sheet feed tray for insertion of a recording sheet into the manual recording sheet feed inlet.

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.
