ABSTRACT:
An electrophotographic transfer film comprising a transparent substrate having formed on at least one side thereof an image-receiving layer is disclosed, in which the image-receiving layer comprises a binder resin and at least one resistivity control agent selected from (a) conductive metal oxide fine particles having an average particle size of not greater than 0.1 .mu.m and (b) an nonionic surface active agent, and the image-receiving layer has a surface resistivity of from 1.times.10.sup.9 to 1.times.10.sup.13 .OMEGA. at 25.degree. C. and 65% RH. The electrophotographic transfer film is less liable to variation of surface resistivity with environmental changes, particularly a great change in humidity, and exhibits excellent transfer properties to provide a toner image of high density in a stable manner.
