Abstract

PURPOSE: To prevent deterioration in the quality of a transferred image due to a residual toner stuck to the surface of a toner image forming member by partially burying fine powder of a substance harder than the member surface in a toner.
CONSTITUTION: Fine powder 3 of a substance harder than the surface of a toner image forming member such as a photosensitive drum is partially buried in toner 2 to manufacture dry toner 1. For example, toner 2 is prepared by melting a heat or pressure fixable resin, after which the molten resin is mixed with a pigment, a charge regulating agent, etc., cooled, and pulverized. Toner 2 is mixed with fine powder 3 and heated toan appropriate temp. to bury powder 3 in toner 2 preferably by about half. Powder of a ≤50μ appropriate grain size range is then separated by classification and used as dry toner 1. No toner 1 remains on the drum surface while sticking to it to prevent deterioration in the quality of a transferred image and the occurrence of a ground stain.
