Abstract
An electrostatic latent image developing device equipped with a developing housing, a developing roller rotatably disposed between the two side walls of the developing housing, and a feeding roller rotatably disposed between the two side walls of the developing housing neighboring the developing roller. A first bearing member is mounted on one side wall and has two bearings for supporting the ends of the rotary shafts of the developing roller and the feeding roller. A second bearing member is mounted on the other side wall and has a bearing for supporting the opposite end of either the rotary shaft of the developing roller or the feeding roller. A third bearing member is mounted on the other side wall and has a bearing for bearing support of the opposite end of the rotary shaft of the developing roller or the feeding roller not supported in bearing fashion by the second bearing member. The second bearing member and the third bearing member are provided with a positioning device for defining a relative positional relationship between the second and third bearing members.
