摘要： A process cartridge (1) includes a first unit (4) including an image bearing member to bear a developing agent image, a second unit (6) including a development frame member in which a developing agent bearing member to bear a developing agent to be supplied to the image bearing member is supported, and a coupling portion (30) configured to couple the first and second units such that the second unit is swingable with the coupling portion as a rotation center. The development frame member includes a replenishing opening for the developing agent, and a sealing member that seals the supply portion and the replenishing opening. As viewed along a compression direction of the sealing member, in a section orthogonal to a longitudinal direction of the process cartridge, the rotation center is disposed at a position overlapping with the sealing member.

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.
