Patent ID: 6990306

Claim:
An image forming apparatus, comprising: an image carrier having a surface roughness Rz not larger than 1.0; a developing device arranged to face said image carrier, housing a developing agent comprising a toner consisting of toner particles and additives mixed with said toner particles, said toner particles containing a binder resin, a coloring agent, and 5 to 7% by weight of a wax, and said additives consisting of 0.08 to 0.6% by weight of silica particles and 0.008 to 0.01% by weight of zinc stearate, the weight ratio of said silica particles to said zinc stearate falling within a range of between 10 and 60, and serving to develop an electrostatic latent image formed on said image carrier so as to form a developing agent image; a transfer device for transferring said developing agent image onto a transfer material; and a fixing device having a heating member and serving to fix the developing agent image transferred onto said transfer material.
