PROBLEM TO BE SOLVED: To provide an electrophotographic toner excellent in all of fixing stability, low-temperature fixing property, offset resistance, and environmental conservation. In an electrophotographic toner containing at least a binder resin and a colorant, the binder resin is mainly composed of a resin (A) and a resin (B), and the resin (A) has a softening point of 120 (° C.). ) To 170 (° C.), the glass transition point is 58 (° C.) to 75 (° C.), the chloroform insoluble fraction is 5 to 50 (mass%), and the resin (B) has a softening point of 90 (° C.) to 120 (° C.), the glass transition point is 58 (° C.) to 75 (° C.), the chloroform insoluble fraction is less than 5 (mass%), and the binder resin has a melting point of 80 (° C.) to The biodegradable resin (C) is 140 (° C.) and has a hydroxyl value of 0.5 (mgKOH / g) to 5 (mgKOH / g).
