摘要： When the acute angle between a normal line, oriented outward from a blade abutting portion of a photosensitive member over which a cleaning blade remains abutted before separation of the surface of the photosensitive member from the cleaning blade, and a horizontal plane, passing through the origin of the normal line, is expressed as a positive value when the normal line lies above the horizontal plane and expressed as a negative value when the normal line lies below the horizontal plane; an imaging unit frame so supports a photosensitive module that the photosensitive member can rotate to a specific rotational position having a greater angle than the angle at the time of separation of the surface of the photosensitive member from the cleaning blade. Until the photosensitive member rotates from a normal rotational position to the specific rotational position, the photosensitive module cannot be removed from the imaging unit frame.

摘要： A waste toner container that collects waste toner that is not used to form an image in an image forming unit of an image forming apparatus, and includes a waste toner collection opening to receive the waste toner output from the image forming unit, a toner amount detector to detect toner amount in the waste toner container, and a waste toner conveyance member disposed inside the waste toner container to convey the waste toner in the waste toner container. The waste toner conveyance member defines a waste toner conveyance direction exchange point, which is a boundary between two different toner conveyance direction regions in which the waste toner is conveyed in opposite directions, and the waste toner conveyance direction exchange point is disposed closer to the toner amount detector than is the waste toner collection opening.

摘要： An image forming apparatus including a cleaning device for removing toner, paper dust and other impurities left on an image carrier after image transfer with a cleaning member is disclosed. The cleaning member contacts the surface of the image carrier with variable pressure and remains, about the time when the image carrier stops moving after image formation, in contact with the surface with pressure lower than pressure capable of scrapping off the impurities. Before movement for image formation, the image carrier is driven in a reverse direction opposite to a forward direction assigned to image formation, stopped, and again moved in the forward direction and then in the reverse direction at least one time.

摘要： In an image forming apparatus, an operating section accessible for entering various information and commands is implemented as a plurality of key units. The key units are each removably connected to the body of the operating section via cooperative connectors. When any one of the key units is damaged or or the life thereof expires, only the defective unit is replaced while the other units are continuously used.
