Abstract

A method of forming a latent electrostatic charge pattern on a photoconductive layer, characterized in that it comprises: electrostatically charging the photoconductive layer of an electrophotographic plate containing a quinacridone pigment and a binder material, said quinacridone pigment having the formula: ** (See formula) ** where R is chosen from the group consisting of CH3, C2H5, OCH3, OC2H5, a halogen and mixtures thereof and where R'is chosen from the group consisting of an aromatic group, a heterocyclic group, an alicyclic group, a group aliphatic and mixtures thereof.
