A developing cartridge (7) is provided. The developing cartridge includes a housing (13) which accommodates developer therein, a receiving member (45) which receives a driving force output member provided in an image forming apparatus, a developing roller (18) which rotates by the driving force received by the receiving member, and a detectable rotary member (50) including a detectable portion (72), which is a detection target to be detected by a detection member provided in the image forming apparatus, and a contact portion (73) which is provided away from the detectable portion. The detectable rotary member rotates from a retreat position to an initial position where the detectable rotary member is rotated by the driving force received by the receiving member, by the contact portion contacting an interference member (91) fixed in the image forming apparatus in a process of mounting the developing cartridge into the image forming apparatus. |
