Abstract

PURPOSE: To obtain a uniform image of sufficient density, by arranging an electrostatic image bearing body and an insulating magnetic toner bearing body in a developing section with a constant gap kept, and allowing a toner to be borne in a thickness smaller than said gap.
CONSTITUTION: When electrostatic image bearing face 1 moves in the arrow direction in a copying apparatus or a recording apparatus, since multipolar permanent magnets 9 are fixed and not rotated, one component type insulating magnetic toner 11 is spread on the surface of nonmagnetic cylinder 4b for bearing toner 11 from developer vessel 12 by rotating cylinder 4b, and an electrostatic charge reverse in polarity to that of the electrostatic image is applied to the toner particles. Sufficient extension of the toner 11 is secured by controlling the gap between face 1 and the toner surface layer up to 3 times the thickness of the toner layer.
