Abstract

PURPOSE:To improve image quality by improving the flowability of magnetic toner by specifying the angles of a restraining magnetic pole and a final carriage magnetic pole, facing a blade, to the center of sleeve rotation. CONSTITUTION:Of the magnet of a sleeve 2 having incorporated magnetic poles which turns magnetic toner 7 counterclockwise, the restraining magnetic pole N1 for restraining the thickness of the toner 7 with a blade 5 and final carriage magnetic pole S2 are set at 80-150 degree angles to the center of the sleeve 2. The angles are set to 100-150, 90-120 and 80-100 degrees for 25mm., 32mm. and 40mm. sleeve outer diameters to maintain the excellent flow states of both pressure-fixing toner and hot-fixing toner. Consequently, no aggregation of the toner, etc., occurs in a hopper 6 and excellent development free of application irregularity, development irregularity, fogging, etc., is achieved.
