  • Patent number: 10444701
    Abstract: Provided are a drive force transmission member and control unit. The drive force transmission member has multiple first engaging portions. Drive force is transmitted from the drive force transmission member to a drive force receiving member with each first engaging portion engaged with a second engaging portion of the drive force receiving member. The second engaging portions are movable in a radial direction centered on a rotation axis line of the drive force transmission member. The control unit performs rotation control of forward rotation of the drive force transmission member by ?° and thereafter backward rotation by ?° after a cartridge is mounted to an apparatus main body but before image formation.
