Abstract
The present invention relates to a photoelectrographic element having a conductive layer in electrical contact with an acid photogenerating layer which is free of photopolymerizable materials and contains an electrically insulating binder and acid photogenerator. A pigment which absorbs near-infrared radiation is included in the photoelectrographic element so that the element, when used in electrostatic copying, can be exposed with near-infrared radiation. A method for forming images with this element is also disclosed.
