摘要： An image forming apparatus comprises: a photosensitive member; a plurality of development devices attachable to and detachable from a main body of the image forming apparatus, a motor; and a drive transmission member. Each development device comprises a development roller for forming a toner image on a surface of the photosensitive member. The motor is rotatable forward and backward, for driving the development roller. The drive transmission member is disposed between the motor and the development roller. The drive transmission member comprising a plurality of gears, a plurality of shafts and a plurality of one-way clutches. An air gap is provided in at least one engagement portion where the gears engage with the shafts.
