A toner cartridge is configured by integrally arranging a fresh toner storing chamber and a residual toner collection chamber. Fresh toner is filled in the fresh toner storing chamber through a fresh toner filling opening. Residual toner is conveyed in the residual toner collection chamber through a residual toner conveying opening. Two residual toner discharging openings are created in the residual toner collection chamber through which the residual toner is discharged.

A cleaning device includes a cleaning blade, a receiving member, an inlet seal, an adhering member, and an end seal. The cleaning blade is brought into contact with a photosensitive drum to remove residual toner therefrom. The receiving member receives the residual toner. The inlet seal guides the residual toner to the receiving member. The adhering member adheres the inlet seal to the receiving member. The end seal is arranged along the end portions of the cleaning blade and the inlet seal. The inlet seal covers the end seal and extends out from the end seal in its longitudinal direction.

An operation to recycle a process cartridge comprising a mechanism for returning waste toner not used in image formation from an image carrier to a developing device can be performed easily, and situations in which an image creating element that has not reached the end of its life is discarded together with an image creating element that has reached the end of its life, making reuse thereof impossible, can be suppressed. The process cartridge comprises an image carrier unit including an image carrier, a developer carrier unit including developing means, and a waste toner conveyance unit having a built-in waste toner conveyance mechanism. These three units are assembled detachably.

A toner recovery device, capable of preventing toner from spilling out of the space between protruding sections and an inner wall of a toner-conveying pipe, and process cartridge and image forming apparatus having this device. Residual toner after transfer, which is carried into a carry-in section of the toner-conveying pipe, is held by the protruding sections of a toner-conveying belt and a bottom surface of the toner-conveying pipe, and conveyed to a carry-out section. Accordingly, the residual toner after transfer can be prevented from oscillating while being conveyed to the carry-out section. Therefore, the residual toner after transfer is prevented from spilling out of the space between the protruding sections and the inner wall of the toner-conveying pipe, and the amount of residual toner after transfer to be conveyed to the carry-out section can be prevented from being reduced.

There is disclosed an image forming apparatus including: a latent image carrier; a latent image writing unit; a development unit; a latent image carrier unit having the latent image carrier; a first positioning protrusion disposed on the latent image carrier unit, the first positioning protrusion being engaged with a groove or a slit of an image forming apparatus body; an abutted portion disposed on the groove or the slit, the abutted portion abutting the first positioning protrusion in order to position the latent image carrier unit in an installation and removal direction; and a second positioning protrusion shifted in the installation and removal direction and disposed on the latent image carrier unit, the second positioning protrusion positioning the latent image carrier unit at a position different from a position of the first positioning protrusion in order to engage the groove or the slit.
摘要:
A developing device configured such that the developing device or the like can be easily inserted and removed without increasing the size of the apparatus, and an image forming apparatus that uses this developing device as well as a process cartridge. The developing device is provided with a first rib formed projecting from a first main wall surface, which is the side surface with the maximum area in the chassis of the developing device, and a second rib formed projecting from a second main wall surface, which is the side surface in opposition to the first main wall surface, the first rib being disposed in a position higher than the second rib in the height direction.
