摘要： A film unit withdrawing apparatus withdraws an exposed film unit from the film pack while permitting it to pass through a pair of pressure rollers. The peel apart type film unit to be used for this apparatus is attached with a tab. This film unit withdrawing apparatus is such that after a photograph is taken, the aforementioned tab is held between and withdrawn by a tab transfer roller and a nip roller. Following the withdrawal of the tab, the pull end of the film unit is ejected by passing between the pressure rollers. Simultaneously, the tab is torn off the film unit. Subsequently, the pull end of the film unit is held between a film unit transfer roller and a nip roller, and the film unit is automatically withdrawn by passing between the pressure rollers.

摘要： An image forming apparatus, includes an image carrier; a power supply; a charging member, to which the power supply applies a direct current (DC) charging voltage, to charge a surface of the image carrier; and a controller. The controller causes the power supply to apply, to the charging member, the DC charging voltage of a sum of a reference voltage VC and a correction amount α, so that a charged potential VD of the surface of the image carrier assumes a target value that is substantially equal to the reference voltage VC; and to increase an absolute value of the correction amount α to be added to the reference voltage VC in inverse proportion to an absolute value of the reference voltage VC, when the absolute value of the reference voltage VC is smaller compared to a case in which the absolute value of the reference voltage VC is greater.

摘要： A belt device incorporatable in an image forming apparatus includes an endless belt, multiple belt tension rollers disposed in contact with an inner surface of the endless belt, a rotary cleaning member to contact a belt wound area of the endless belt facing an opposing roller to form a cleaning nip between the rotary cleaning member and the endless belt and rotate the rotary cleaning member in a direction opposite the belt moving direction within the cleaning nip, and a voltage applier. The cleaning nip is formed by offsetting a center of the cleaning nip upstream from a center of the belt wound area of the endless belt in the belt moving direction and by at least contacting the rotary cleaning member in a range from the belt wound area to a tensioned belt area located upstream from the belt wound area in the belt moving direction.

摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.
