Abstract
A toner for electrophotography is so prepared that a wax in a binder resin has an average diameter in the range from 0.1 to 3.0 μm so as to alleviate hot offsetting and filming, and that the toner contains 1.0 to 2.5% by volume of a fine particle toner with particle diameters of 5.04 μm or smaller so as to grind, at an early stage, the toner components that have attached to a photoconductor and thereby prevent filming.
