Abstract:
1. A developing device for developing an electrostatic latent image formed on an electrophotographic photoreceptor, comprising: a hollow developing roller having an inner surface; a support member inserted in the developing roller to support the developing roller, the support member having an outer surface; a flange member having a first engaging portion engaging with the outer surface of the support member and a second engaging portion engaging with the inner surface of the developing roller; and a gap-holding member disposed at one end of the developing roller, the gap-holding member having an abutment abutting against the electrophotographic photoreceptor so as to maintain a gap between the developing roller and the electrophotographic photoreceptor, wherein the abutment overlaps with the second engaging portion in the longitudinal direction of the developing roller.
