Claim 0:
1. An image forming apparatus forming an image on a recording material, the image forming apparatus comprising:
a restricting member;
a driven gear that includes a portion to be restricted capable of coming into contact with the restricting member, wherein rotation of the driven gear in a restriction direction is restricted when the portion to be restricted is in contact with the restricting member;
a planetary gear mechanism that includes an input portion configured to receive a driving force transmitted from a driving source, an output portion configured to transmit the driving force to the driven gear, and a portion to be stopped; and
a stopping member that is configured to stop rotation of the portion to be stopped in a first rotation direction, and allow rotation of the portion to be stopped in a second rotation direction opposite to the first rotation direction, wherein
when the input portion rotates in a first direction, the stopping member stops rotation of the portion to be stopped in the first rotation direction, and the output portion rotates the driven gear in a release direction opposite to the restriction direction, and
when the rotation of the driven gear in the restriction direction is restricted and the input portion rotates in a second direction opposite to the first direction, the portion to be stopped rotates in the second rotation direction.
