Abstract
An image forming apparatus includes a photoconductor drum, a developing roller, a first shaft provided for one of the photoconductor drum and the developing roller, a second shaft provided for the other of the photoconductor drum and the developing roller, a first housing that supports the first shaft, a second housing that supports the second shaft, a cylindrical supporting member provided at an axial end portion of the first shaft of the first housing, and surrounding the first shaft without contact, and a first adjusting member fitted with an outer surface of the supporting member, and rotatable in a circumferential direction of the supporting member. An outer circumferential surface of the first adjusting member is formed in an arcuately curved shape, eccentric with respect to the supporting member, and located in contact with the second housing.
