Abstract
The invention relates to a transmission device for engagement with a photosensitive drum having a drum axis L, where a sleeve is coaxially coupled to the photosensitive drum. The transmission unit includes a shaft that is rotatable about the drum axis L relative to the sleeve and movable along the drum axis L relative to the sleeve and has a base at one end of the shaft; and at least two engagement blocks extending from two opposite sides of the base away from the drum axis L, where each engagement block is rotatable around a pivotal axis provided at the two opposite sides of the base, and the pivotal axis is perpendicular to the drum axis L. Accordingly, the transmission device can be connected with and separated from the drive member smoothly.
