Abstract
This invention is directed to photosensitive material for electrophotography and more particularly it is directed to the improvement of the properties with respect to humidity of photosensitive material by using photoconductive material in combination with ion exchange resin or by using photoconductive material which is previously washed in an aqueous solution in the presence of ion exchange resin.
