ELECTROPHOTOGRAPHIC FULL COLOR TONER

摘要

PROBLEM TO BE SOLVED: To provide a full color toner having gloss and transparency and realizing both of low temperature fixing property and hot offset resistance. SOLUTION: The electrophotographic full color toner contains at least a resin A, a resin B and wax. These components form a sea-island phase separation structure in an insoluble state with one another and satisfy the following conditions (1) to (5). (1) The sea-island phase separation structure has the island- like resin B dispersed in the sea-like resin A as a continuous phase, and the wax is substantially encapsulated in the island-like resin B. (2) The binder resin in the toner does not have a THF insoluble component. (3) The resin A is essentially a polyester and/or polyol and the resin B is a copolymer resin of styrene and methylacrylate and/or methylmethacrylate. (4) The contents of the resin A, B and wax are in the relation of resin A>resin B>=wax. (5) The wax content ranges from 2 wt.% to 15 wt.%.
