Abstract
The invention relates to a transmission device for engagement with a photosensitive drum having a drum axis, comprising a shell detachably attached to the photosensitive drum coaxially to the drum axis; a sleeve coupled with the shell coaxially to the drum axis, such that the shell and the sleeve define at least one guiding groove therebetween; and a transmission unit comprising a shaft disposed to the sleeve coaxially to the drum axis, such that the shaft is rotatable about the drum axis relative to the sleeve and movable along the drum axis relative to the sleeve, wherein ranges of the rotation and motion of the shaft relative to the sleeve are subjected to the at least one guiding groove. Accordingly, the transmission device can be connected with and separated from the drive member smoothly.
