Method of assembling a developing apparatus

Abstract

A method of assembling a developing apparatus comprises, forming a recess in the outer circumference of a pair of holding members, fitting a first positioning pin of an adjustment jig into the recess without a clearance, after the fitting, fitting a concave support member on a second positioning pin without a clearance, and positioning and mounting them, after the fitting, separating the first and second positioning pins of the adjustment jig from the recess and the support member, after the separation, assembling a pair of holding members in one body with a predetermined interval, and after the assembly, mounting a plurality of developing rollers by fitting both ends of the center shaft into the recess of the pair of holding members and the concave support member, respectively.

1 . A method of assembling a developing apparatus comprising: 
 forming a recess in the outer circumference of a pair of holding members;    preparing an adjustment jig having a first positioning pin and a second positioning pin, and fitting the first positioning pin of the adjustment jig into the recess without a clearance;    after said fitting, fitting a concave support member on the second positioning pin without a clearance, and positioning and mounting them on the outer circumference of the holding member;    after said fitting, separating the first and second positioning pins of the adjustment jig from the recess and the support member;    after said separation, assembling said pair of holding members in one body with a predetermined interval; and    after said assembly, mounting a plurality of developing rollers by fitting both ends of the center shaft into the recess of said pair of holding members and the concave support member, respectively.
