BIAS SUPPLYING STRUCTURE OF DEVELOPING

摘要

PURPOSE: A bias supplying structure of developing is provided to decrease a number of component and save a separate manufacturing cost by injecting and forming a magnet and a rotating axis as one body. CONSTITUTION: A rotating axis(32) is formed to a center of both sides of a magnet member(30). Both sides of the rotating axis(32) is made as a plastic material. A flange(36) for forming a transmission hole(34) is inserted into a center of the rotating axis(32). A coil spring(38) for providing a bias is contacted to an inner surface of a front end of a sleeve(16) of the magnet member(30). Upper and lower coils(40,42) of the coil spring(38) are connected as one body. One end of the lower coil(42) is contacted to an external surface of the front end of the sleeve(16).
