Abstract
A process for producing a composite resin for a toner, comprising the steps of: mixing, in water, (a) a low-molecular weight polymer powder comprising particles, not less than 80% by weight of the particles having a diameter of from 20 to 2000 microns with (b) a high-molecular weight polymer emulsion; subjecting the thus obtained mixture to a coagulation treatment; and heating the resulting mixture to obtain a composite resin in which the low-molecular weight polymer particle and the high-molecular weight polymer are fixed and homogeneously mixed with each other.
