Abstract

A toner for electrophotography is disclosed. The toner comprises a binder resin and a colorant and a wax in amount of 0.5 to 8 percent by weight, and adhesion power index of wax particles to toner particles is between 0.7 and 2.2. The toner improves the durability of the developer material and a photoreceptor, minimizes image smear at high temperature and humidity, and exhibits excellent fixation as well as offsetting resistance.
