Abstract
A developing cartridge includes: a casing having a groove recessed inward; a developing roller having an outer circumferential surface; a blade; and a blade holder having a first plate and a second plate. The developing roller is rotatable about a rotational axis extending in a first direction. The blade regulates a thickness of toner layer on the outer circumferential surface. The blade has one end portion and another end portion in a second direction. The another end portion of the blade is positioned farther from the outer circumferential surface than the one end portion of the blade is from the outer circumferential surface. The first plate extends in the second direction and supports the another end portion of the blade. The second plate extends from the first plate in a third direction crossing the second direction to have a distal end portion positioned within the groove.
