PURPOSE:To obtain a toner for electrostatic charge image capable of preventing generation of offsetting phenomenon while retaining low temp. fixation by using an epoxy resin compsn. consisting of a specified epoxy resin mixed with a polyfunctional cyanic acid ester or its prepolymer, and a curing catalyst therefor. CONSTITUTION:An epoxy resin compsn. consisting of 100pts.wt. epoxy resin having 60-160 deg.C m.p., 0.5-10pts.wt. polyfunctional cyanic acid ester having >=2 cyanate groups in a molecule or a prepolymer thereof as a component (a), and an org. peroxide such as benzoyl peroxide, lauroyl peroxide for promoting the curing of the component (a) as the component (b), is used as binder. Thus, a toner capable of retaining low temp. fixation and generating no offsetting phenomenon is obtd. |
