ABSTRACT:
A film for electrophotographic transfer comprising a transparent plastic film having a heat resistance temperature of 100.degree. C. or higher having provided on at least one side thereof a transparent resin layer, wherein the transparent resin layer comprises a polyester resin having a peak count value (A) in GPC molecular weight measurement which satisfies relationship: -30.ltoreq.A-B.ltoreq.+20, in which B is a peak count value of the binder resin of a color toner used for fixing, and an initial count value (Cp) in the GPC molecular weight measurement which satisfies relationship: -500.ltoreq.Cp-Ct.ltoreq.-200, in which Ct is an initial count value in the GPC molecular weight measurement of the binder resin of a color toner used for fixing, or a polyester resin having a weight average molecular weight of from 15000 to 40000 and a weight average molecular weight to number average molecular weight ratio of from 3.5 to 10; the transparent resin layer has a thickness of from 1 to 8 .mu.m, and the transparent resin layer forms a contact angle of not more than 50.degree. with a color toner to be fixed thereon in a molten state at a fixing temperature.
