Abstract

A driving force transmission device (5) includes a first driving member (61), a second driving member (71), a moving member (50) and a connection drive section (5A). The connection drive section (5A) separates, in conjunction with movement of the moving member (50) in the first direction, the first driving member (61) and the second driving member (71) respectively from a first rotating member (121) and a second rotating member (124A) in such a manner as to cause a time difference between a separating operation for separating the first driving member (61) from the first rotating member (121) and a separating operation for separating the second driving member (71) from the second rotating member (124A).

Description

technical field [0001] The present invention relates to a drive transmission device that transmits a driving force to a rotating body, and an image forming apparatus including the drive transmission device. Background technique [0002] Generally, in an image forming apparatus that forms an image on a sheet, various rotating bodies are driven to rotate. As a rotating body, the photosensitive drum and the developing roller arranged in the developing device are arranged in the main body of the image forming apparatus. The developing roller is rotatably supported by the developing device. In addition, the rotation axis of the photosensitive drum and the rotation axis of the developing roller are arranged parallel to each other. [0003] The photosensitive drum and the developing device are respectively attachable and detachable with respect to the apparatus main body. Therefore, the coupling gear that transmits driving force to the photosensitive drum and the developing roll...
