Electrostatic latent image developer with shaft bearing members

An electrostatic latent image developing device equipped with a developing housing, a developing roller rotatably disposed between two side walls of said developing housing for holding developing agent on a peripheral surface thereof and for applying the thus held developing agent onto an electrostatic latent image, and a feeding roller rotatably disposed between the two side walls of said developing housing and neighboring said developing roller in order to feed the developing agent onto the peripheral surface of said developing roller, comprising:

• a first bearing member mounted on one side wall of said developing housing and having two bearings for supporting a first end of a rotary shaft of said developing roller and a first end of a rotary shaft of said feeding roller;
• a second bearing member mounted on the other side wall of said developing housing and having a positioning boss with an insertion hole by which is temporarily supported a second end of the rotary shaft of one of said developing and feeding rollers;
• and
• a third bearing member mounted on the other side wall of said developing housing and having a bearing for supporting a second end of the rotary shaft of the other of said developing and feeding rollers;
• said third bearing member being provided with a fitting recess which fits to said positioning boss provided on said second bearing member, and an end wall forming said fitting recess being provided with a bearing for supporting the second end of the rotary shaft inserted in said insertion hole formed in said positioning boss.
