Claim 0:
1. An image forming apparatus comprising:
a drive source;
an object configured to be driven by the drive source; and
a drive transmission mechanism configured to transmit driving force from the drive source to the object, the drive transmission mechanism including
a driving member connected to the drive source and configured to be rotated around an axis by the driving force,
a driven member connected to the object and configured to rotate around the axis, the driven member including an engaged portion,
an intermediate member configured to rotate integrally with the driving member around the axis, the intermediate member including an engagement portion,
an urging member configured to urge the intermediate member toward a first side in an axial direction of the axis, and
an actuating portion configured to act on the intermediate member,

wherein the intermediate member is configured to move in the axial direction to a first position in which the engagement portion of the intermediate member is engaged with the engaged portion of the driven member such that the driving force is transmitted to the driven member, and to a second position in which the engagement portion of the intermediate member is separated from the engaged portion of the driven member such that the driving force is not transmitted to the driven member, the second position being on a second side of the first position in the axial direction, the second side being opposite to the first side,
wherein the intermediate member includes a shaft portion extending in the axial direction, and the shaft portion includes a positioning portion configured to determine a position of the driven member in a direction orthogonal to the axis,
wherein the shaft portion further includes a receiving portion configured to receive a force, by which the intermediate member is moved from the first position to the second position, from the actuating portion, and
wherein the receiving portion is positioned inward of the positioning portion in a radial direction of rotation of the intermediate member.
