摘要： Disclosed is a cartridge attachable/detachable to/from an apparatus body of an image forming apparatus. A bearing member for pivotally supports a rotation member has an engaged portion that is arranged at a part on one end side of the cartridge in a direction of a rotational axis of the rotation member and engaged with an engaging portion provided in the apparatus body. An engagement state between the engaged portion and the engaging portion is maintained until at least a coupling of the rotation member is coupled to a driving shaft provided in the apparatus body in a process of attaching the cartridge to the apparatus body. A movement of the bearing member to at least the other end side in the direction of the rotational axis with respect to the apparatus body is restricted when the engaged portion and the engaging portion are put into the engagement state.

摘要： A flange member (63) includes a first cylindrical portion (63a), a second cylindrical portion (63b) disposed inside the first cylindrical portion (63a) coaxially with the first cylindrical portion (63a), an inwardly protruding portion (63e) protruding from an inner circumference of the second cylindrical portion (63b), a first wall (63f1), a second wall (63f2) opposed to the first wall (63f1), and a connecting portion (63f3). The first wall (63f1) connects the first cylindrical portion (63a) and the second cylindrical portion (63b) and is in contact with a shaft member (75) between the first wall (63f1) and the second wall (63f2) to receive a driving force. The connecting portion (63f3) connects the first cylindrical portion (63a) and the second cylindrical portion (63b) and connects the first wall (63f1) and the second wall (63f2). A groove (63g) is provided inside the first cylindrical portion (63a) and outside the second cylindrical portion (63b).

摘要： A feeding device for feeding a developer includes a cleaning member, an accommodating portion, a feeding member, and a sheet member. A wall surface of the accommodating portion is positioned in a side where the sheet member is provided with respect to a rectilinear line connecting a rotation center of the image bearing member and a rotation center of the feeding member in a flat plane perpendicular to an axial direction of the image bearing member. The wall surface approaches the rectilinear line with an increasing level with respect to a vertical direction. The feeding member is provided vertically above a position where the cleaning member contacts the image bearing member. A rotational direction of the feeding member and a rotational direction of the image bearing member are the same.
