Abstract

PURPOSE: To effect uniform development and to elongate the life time of a developing agent by providing a developing agent reservoir in the housing of a developing device for zerographic copy so that the developing agent may be partially received from the developing position while discharging the same quantity into a magnetic brush chamber.
CONSTITUTION: A magnetic brush chamber 3, which is formed on its surface with a magetic brush 11 and which is equipped with nonmagnetic cylinders 8, 9 and 10 having multi-polar magnets 5, 6 and 7 built therein and with stirring members 13 and 14, is separated from a developing agent reservoir 4 by means of a partition 2. There is mounted in the reservoir 4 a feeder shaft 15 which carries blades 16 and 17 and which is adapted to rotated in the direction of arrow d. The feeder shaft of the reservoir is turned at a preset speed while turning the cylinders 8, 9 and 10 and the stirring members 13 and 14. Then, a portion of the developing agent flows into an inlet 4A and is stirred and blended by the blades 16 and 17 so that the development agent of the same guantity is discharged from an outlet 4B to the magnetic brush chamber 4.
