Abstract

PURPOSE:To obtain a toner with superior suitability to coating onto a magnetic sleeve and uniformly and thickly coating power by adding cyclized rubber to a pressure fixing magnetic toner. CONSTITUTION:A pressure fixing component such as low molecular polyethylene, magnetic powder and cyclized rubber are mixed with a solvent such as toluene and converted into a toner with a spray dryer. The amount of the rubber mixed is 1.5-20wt% of the amount of the toner. The constituent solid substances of the toner may be pulverized finely to obtain the toner. To the toner composition may be added other resin or wax to improve the chargeability, transferability and cleanability within a range where no unfavorable influence is exerted on the pressure fixability. In a developing process, in order to stably hold one-component magnetic toner 11 fed from developer container 12 on a sleeve, nonmagnetic cylinder 4b contg. multipolar permanent manget 9 is used as the sleeve. In addition, doctor blade 10 made of magnetic sheet or permanent magnet is set in the vicinity of the surface of cylinder 4b to uniformly form a toner layer.
