Organic photoconductive elements which are stable and sensitive over a broad range of the spectrum, including the near infrared band, having a charge generating layer and a charge transport layer carried on an electroconductive support are disclosed. The invention involves the use of a first layer between the support and the charge generating layer which is capable of functioning as (i) an adhesive bonding layer on the electroconductive support to provide a receptive and retentive base layer for the charge generating layer and (ii) as a barrier layer to prevent substantially any leakage of charge from the surface of the photoconductor, characterized by the first layer comprising at least one polycarbonate having a weight average molecular weight ranging from about 25,000 to about 45,000, in combination with a charge generating layer that comprises at least one organic pigment which is sensitive to near infrared radiation.
An organic photoconductive element which is extremely sensitive to exposure to light rays in the near-infrared region of the spectrum, said element comprising an electroconductive plastic film support;
A method for forming an electrophotographic image comprising:
