<P>PROBLEM TO BE SOLVED: To provide a cartridge improved in a mounting operability in mounting a coupling. <P>SOLUTION: The cartridge includes: a coupling 150 for receiving a rotational force for rotating a developing roller from a main assembly, in a state in which the cartridge is mounted to the main assembly; a cylindrical member 147 movably supporting one end portion of the coupling in a movable manner; a cylindrical member side force receiving portion 147h for receiving the rotational force received from the main assembly by the coupling; a first regulating portion 147k provided so as to be deformed in a radial direction of the cylindrical member, for preventing one end portion of the coupling from disengaging in an axial direction of the cylindrical member; and a second regulating portion 157a for regulating deformation of the first regulating portion in a state in which one end portion of the coupling is mounted to an inside of the cylindrical member with deformation of the first regulating portion. <P>COPYRIGHT: (C)2010,JPO&INPIT |
