A developing device includes a main body that is arranged between a pair of supporting members and includes a developing roller. Both end portions of the developing roller are supported by the supporting members in a first direction in which the developing roller is movable toward and away from an image carrier. A groove is formed on each of the supporting members. Either one of an end portion of the developing roller and a bearing that supports the end portion is inserted into the groove. Either one of at least one of the end portions of the developing roller and at least one of the bearings is movable in the groove in a second direction that intersects the first direction.

A waste-toner collecting device includes a cleaning unit that collects waste toner remaining on an image carrier; a conveying belt that conveys the waste toner collected by the cleaning unit in a first direction; and a conveying screw that conveys the waste toner conveyed by the conveying belt in a second direction. An end of the conveying screw on a side of the conveying belt is rotatably supported by an inner wall of a body of the waste-toner collecting device in a state where the end of the conveying screw is in contact with the inner wall.

The present invention relates to a composite lens and a method for manufacturing the same, particularly to a composite lens in which a second lens component is coupled to a first lens component at part of a first surface, and intends to improve optical characteristics. A composite lens (1) has a first lens component (10) and a second lens component (20). The first lens component (10) has a first surface including a first lens surface (13), a peripheral surface (15a) surrounding the first lens surface (13) and a ring surface (17a) included in the peripheral surface (15a) and surrounding the first lens surface (13), and a second lens surface (12) on the opposite side of the first lens surface (13). The second lens component (20) is coupled to the first lens component (10) at part of the first surface surrounded by the ring surface (17a). The ring surface (17a) is positioned on a portion of the first lens component protruding from a joint portion (14) between the first lens surface (13) and the peripheral surface (15a) in a first direction from the second lens surface (20) to the first lens surface (10) along an optical axis of the first lens component (10) and is exposed out of the second lens component (20).

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.
摘要:
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.

A method for manufacturing an optical element comprises a step of press molding an optical element material 6 disposed between an upper press head (7) and its paired lower press head (8), wherein in the upper press head (7) and/or the lower press head (8) is formed a groove-like component that forms a non-cylindrical face or a cylindrical face as an optically effective component in the optical element material (6). This makes it possible to obtain an optical element with stable face shape precision, boosts productivity, and is also advantageous in terms of cost.
