Abstract:
1. A drive transmission apparatus, comprising: a first gear that is driven by a drive source, wherein the first gear is rotated in a first direction and a second direction opposite to the first direction by the drive source; a second gear; a supporting member configured to support the second gear capable of revolving around the first gear in a rotatably engaged state with the first gear; a driven gear engaging with the second gear when the second gear revolves to an engagement position due to the rotation of the first gear in the first direction; and a rotational force providing unit configured to provide a rotational force to the driven gear to rotate the first gear in the second direction via the second gear when the second gear is engaged with the driven gear, wherein when the first gear is rotated in the second direction by the drive source, the second gear receives a rotational force via the driven gear and the rotational force prevents the second gear from revolving around the first gear.
