ABSTRACT:
In order to provide a driving mechanism for a photosensitive drum which is capable of reducing deformation of the shaft of the photosensitive drum caused by loads when transmitting a driving force, a drive transmission course 51 is diverged to at least two courses in a drive transmission system 42 for transmitting the drive force from a drive motor 41 to the photosensitive drum 25. Specifically, the last stage of the drive transmission course 51 is engaged with a passive member 47 provided to the drum shaft 25a at two or more points to connect and link the drive force, thereby diverging the directions of loads to several directions, by which irregular movements of the photosensitive drum or vibration caused by the deformation of the shaft is eliminated.
