Abstract

An image forming apparatus including a photosensitive drum, a development roller, a separation cam, a fixing device, an adjusting cam, a main motor, a separation gear train, a fixing gear train, and an adjusting gear train. The development roller is movable relative to the photosensitive drum between a contact position and a separate position. The adjusting cam switches a nip pressure of the fixing device between first and second pressures. The separation gear train transmits a driving force of the main motor to the separation cam. The fixing gear train transmits the driving force of the main motor received from the separation gear train to the fixing device. The adjusting gear train transmits the driving force of the main motor received from the separation gear train to the adjusting cam.
