A developing roller (12) is located closer to a first end (113) than to a second end (114) of a housing (11) in a first direction. A first boss (13) extends in a second direction and is movable together with the housing. The first boss bears the weight of a developer cartridge (1) when the first boss is supported by a support surface (41) of a first side plate (33) of a drum unit (3), and is located away from the developing roller in the first direction and the third direction. A first pressure receiving surface (15) is located farther away from the developing roller than the first boss is in the third direction. The pressure receiving surface receives a pressing force in the third direction from a pressing member (47) of the first side plate of the drum unit. The first boss is located away from the developing roller in the first direction by a first distance (D1). The first pressure receiving surface is located away from the developing roller in the first direction by the first distance or by a second distance (D2) smaller than the first distance.
