摘要： An image forming apparatus includes a photosensitive member, a developing unit which is removably installed in a body of the image forming apparatus, a shutter covering a developing region of the photosensitive member when the developing unit is removed from the body of the image forming apparatus and a cleaning member capable of cleaning the surface of the photosensitive member in accordance with rotation of the photosensitive member by making contact with the photosensitive member in conjunction with the shutter covering operation, but which does not contact the photosensitive member when the shutter is open. During a control operation, foreign matter such as used developer adhered to the photosensitive member is removed when the photosensitive member is rotated with the shutter closed.

摘要： An image forming apparatus comprising a laser beam radiating unit utilized as a light source, and an optical system that the surface of an original reflects a laser beam radiated from the radiating unit to project an image reflected from the original onto a photosensitive member. In this apparatus, an image is formed selectively in a print mode so that an image results from turning on and off the laser beam, in a copy mode that a copy of an original results from exposure of the photosensitive member to the laser beam reflected from the surface of an original or in a composite mode that a composite image is formed of a copy of an original and an image resulting from turning on and off the laser beam. Further, this apparatus comprises a projection lens unit for projecting an image reflected from an original onto the photosensitive member. The laser beam transmitting through the lens unit is scanned in the direction perpendicular to the main scanning direction, and altering the scanning speed and position of the lens unit results in various magnifications of an image.

摘要： A developing device has a bearing member that can bear a toner, a storing chamber for storing the toner, a waiting chamber disposed below the storing chamber for receiving the bearing member that can be filled with the toner and a buffer chamber positioned between the storing chamber and the waiting chamber for storing the developer material. A first horizontal connecting path connects upper portions of the storing and buffer chambers, and two second connecting paths connect lower portions of the buffer chamber and the waiting chamber. A feed member feeds toner from the storing chamber through the first connecting path into the buffer chamber. A first conveying member in the buffer chamber conveys the toner from one of the connecting paths to the other of the connecting paths, and a second conveying member in the waiting chamber conveys the toner within the waiting chamber in the opposite direction.
