Abstract: A developer storage container includes a main body portion and a rotary cylindrical body. The main body portion has a cylindrical inner peripheral surface and a pair of main body side end surfaces. The rotary cylindrical body has a side surface having a cylindrical shape, a pair of rotary body end surfaces and a storage space configured to store developer. A slit extending is formed on the side surface of the rotary cylindrical body to allow communication between the internal space and the storage space. The rotary cylindrical body is so arranged in the internal space that a predetermined clearance is defined between the side surface and the inner peripheral surface of the main body portion. A developer discharge port is opened on the main body portion.

Abstract: A sheet storage device includes a sheet positioning member that is movable in a first direction, and positions a sheet by abutting on a side end portion of the sheet at a side in the first direction. The sheet positioning member includes a moving body, an abutting portion, a first and a second biasing member, and a bias removing portion. The moving body is configured to move in the first direction. The abutting portion is supported by the moving body to be movable in the first direction and configured to abut on the side end portion when the sheet positioning member positions the sheet. The first biasing member biases the abutting portion toward the side end portion. The second biasing member biases the abutting portion against a biasing force of the first biasing member. The bias removing portion removes a bias applied by the second biasing member.

Abstract: A sheet guide of an image forming apparatus includes a first upstream guide member and a first downstream guide member. The first upstream guide member includes an upstream front guide surface and an upstream rear guide surface. The first downstream guide member includes a downstream front guide surface and a downstream rear guide surface. The downstream front guide surface intersects with an imaginary plane formed by extending, toward a downstream side in a conveyance direction of a sheet, the upstream rear guide surface. The upstream front guide surface intersects with an imaginary plane that is formed by extending, toward an upstream side in the conveyance direction, the downstream rear guide surface. When viewed from a direction perpendicular to the upstream rear guide surface, an edge portion of the first upstream guide member on the downstream side is inclined with respect to a width direction perpendicular to the conveyance direction.

Abstract: A driving apparatus includes a driving input gear with first gear teeth, a columnar shaft, and a driven gear that engages the driving input gear. The driven gear includes a cylindrical boss portion, a cylindrical rim portion, a web, and second gear teeth. The second gear teeth are formed at an outer peripheral surface of the rim portion. The first gear teeth are first helical teeth twisted in a first direction with respect to a direction that the rotary drive shaft extends. The second gear teeth are second helical teeth twisting in a second direction that is the opposite of the first direction. The rim portion is tapered, radially decreasing toward the end to which the web is linked. The through-hole of boss portion has an inner diameter larger than an outer diameter of the shaft.

Abstract: A developer container (30) includes a container body (31) and a movable wall (34). The container body (31) includes an inner surface (31K) defining a cylindrical internal space (31H) extending in a longitudinal direction, and a developer discharge port (319). The developer discharge port (319) is formed in a lower part of the inner surface (31K). The movable wall (34) includes an outer surface (34K) disposed slidably in contact with the inner surface (31K) of the container body (31), and a conveying surface (340S). The conveying surface (340S) defines a storage space (31S) for containing developer in cooperation with the inner surface (31K). The movable wall (34) moves in the longitudinal direction from one end side toward the other end side while conveying the developer in the storage space (31S) to the developer discharge port (319).

Abstract: The sheet feeding cassette includes a cassette frame, a first lift plate and a second lift plate. The cassette frame includes a bottom plate and side plates extending in the feeding direction. The bottom plate and the side plates form a sheet placement space. The first lift plate is disposed on the bottom plate, configured to rotate up and down around a first axis extending along a width direction perpendicular to the feeding direction, and configured to lift a leading end portion in the feeding direction of the sheet. The second lift plate is configured to rotate up and down around a second axis extending along the feeding direction and to lift a side end portion along the feeding direction of the sheet.
