Abstract

PURPOSE: To enhance faithfullness and stabilize image quality by letting insulation- type magnetic developer transfer onto an electrostatic image holding body under the effect of magnetic fiels to develop in an electrophotographic method.
CONSTITUTION: An electrostatic image holding body 1 which holds electrostatic images on the surface and a developer carrying body 4b which carries insulation- type magnetic developer 11 on the surface are disposed by providing a fixed spacing, and the development is accomplished by letting the developer 11 containing 10W 50wt% of magnetic powder be carried on the carrying body 4b to a thickness thinner than the spacing and letting the developer 11 be transferred to the holding body 1 under the effect of magnetic field. Thereby, the stable image quality of high faithfullness may be obtained.
