Electrophotographic element and indirect electrophotographic process for the production of copies with this electrophotographic element which contains a photoconductive pigment dispersed in a binder, which binder is a copolymer of an acrylic or methacrylic acid ester monomer, a vinyl aryl monomer and 1-3% by weight unsaturated acid, in said copolymer 2.5 to 6 parts by weight of copolymerized vinyl aryl monomer being present per part by weight of copolymerized acrylic or methacrylic acid ester monomer. …<??>Herewith is prevented that, after repeated use of the electrophotographic element, contours of smaller sized images become visible on larger sized images produced after the smaller images. |
