Abstract
A developing cartridge includes a developing roller 210d that develops, by way of a developer, an electrostatic latent image that is formed on an image bearing member 207; a developer regulating member that regulates the thickness of a developer carried on the developing roller 210d; and a frame 214a that rotatably supports the developing roller 210d and supports the developer regulating member. The frame 214a has a developing roller support section 214a1 that rotatably supports an outer peripheral face 210d6 of at least one end of the developing roller 210d. The developing roller support section 214a1 has a clearance at a position that, when viewed in the axial direction of the developing roller 210d, overlaps a contact region at which the developing roller 210d is in contact with the image bearing member 207.
