ABSTRACT:
A drive unit includes a motor being a drive source, a velocity reduction gear for reducing the revolution of the motor, an output shaft for connecting the velocity reduction gear to the rotation shaft of a photosensitive drum, and a velocity detection mechanism including an encoder and sensor members and detecting the revolution of the output shaft. The velocity reduction gear and the velocity detection mechanism are placed in a unit housing including a housing body made of a resin with one end opened and a support plate made of metal closing the opening of the housing body, and the output shaft is rotatably supported by the housing body and the support plate.
