Abstract

PURPOSE: To make developing concentration sufficient and prolong the life of the developer by mixing noncoating carrier and coating carrier and using the mixture.
CONSTITUTION: The coating carrier comprising covering the surfaces of ferromagnetic material with dielectric films and the non-coating carrier composed of ferromagnetic material alone are mixed. The carrier composed of this mixed power and toner are mixed, whereby the developer for electrophotography is obtained.
