Abstract: A cleaning device for an image forming apparatus includes a cleaning member that removes residual developer that remains on a image carrier, a rotary conveying member that conveys the removed residual developer toward a predetermined direction, and a housing that contains the rotary conveying member. The housing includes a support member that supports the cleaning member; and a protective member that has an inner wall which opposes outer periphery of the rotary conveying member and partially covers the rotary conveying member. The protective member is made of a resin molding material to which a filler is not added.

Abstract: A developer storage body includes a housing in which a developer is stored, a shutter portion mounted to the housing and having a hole portion through which the developer is replenished into the housing, and a cap portion covering the hole portion. The cap portion includes a structural portion that constitutes an enclosure body enclosing a hollow portion. The structural portion is formed of a first material. The cap portion further includes a seal portion that covers the structural portion to seal the hollow portion. The seal portion is formed of a second material having a lower flexural modulus than the first material.

Abstract: A developer collection container includes: a container body capable of containing collected developer; a developer conveyance member extending into the developer collection container and configured to convey the developer into the container body; and a guide provided in the container body and supporting the developer conveyance member from below the developer conveyance member.

Abstract: A cleaning device includes a cleaning member for removing developer attached to a developer attaching member; a rotation carrying member which is rotatably configured to carry the developer that is removed by the cleaning member; a housing member for housing the developer that is removed by the cleaning member and configured as a part of a developer housing part that surrounds the rotation carrying member; and an elastic member arranged to contact a periphery of the rotation carrying member.

Abstract: A developing device includes a storage portion for retaining developer; a light guide member for forming a plurality of optical paths passing through the storage unit to detect an amount of the developer in the storage portion; a plurality of window members formed in a wall of the storage portion for passing the optical paths therethrough; a blocking member disposed to be movable for blocking the window members; and a drive unit for moving the blocking member. The blocking member is disposed on each of the optical paths. When the drive unit moves the blocking member, the blocking member periodically blocks and opens each of the optical paths in a specific cycle.

Abstract: An image forming apparatus that is capable of solving the problem of abrasion or load caused by an unevenly installed cleaning member and capable of realizing excellent cleaning performance. A cleaning section in the image forming apparatus has a cleaning member in the shape of a board, which contacts the surface of the charging roller through it's a first surface, and a fixing member, which supports the cleaning member at least at an upstream side of a contact position between the charging roller and the cleaning member with respect to the rotation direction of the charging roller. The fixing member is formed so as to not contact the cleaning member in an area of a second surface which is opposite to the contact part of the charging roller and the cleaning member.

Abstract: An image forming apparatus is provided capable of solving such problem of abrasion or load caused by the unevenness of installation position of cleaning member and capable of realizing excellent cleaning performance. A cleaning section in the image forming apparatus has a cleaning member with board shape which contacts with the surface of the charging roller through it's a first surface; and a fixing member which supports the cleaning member at least at an upstream side than a contact position between the charging roller and the cleaning member with respect to the rotation direction of the charging roller, the fixing member is formed so as to not contact with the cleaning member in an area of a second surface which is opposite to the contact part of the charging roller and the cleaning member.
