    • Disclosed is an adhesive generating layer for use in an overcoated photoreceptor system, this layer containing a generating pigment dispersed in a copolymer of a siloxane and a dihydroxy compound of the formula: ##STR1## wherein R and R' are independently selected from the group consisting of alkyl, substituted alkyl, alkenes, substituted alkenes, aryl and substituted aryl; Y is a dihydroxy radical; and n is a number of sufficient value that the average molecular weight of the resulting silicone copolymer is between about 2,000 and 250,000. Examples of copolymers include those wherein R and R' are alkyl groups such as methyl and Y is a biphenol such as 2,2-bis-(4-hydroxy phenyl)-propane, one preferred material being a methyl octyl siloxane 2,2-bis-(4-hydroxy phenyl)-propane copolymer. Examples of pigments that are dispersed in the generating layer include metal free phthalocyanines, such as X phthalocyanine, alpha phthalocyanine, beta phthalocyanine, metal phthalocyanines such as vanadyl phthalocyanine, selenium, selenium containing compounds such as selenium alloys including selenium arsenic, selenium bismith, and other types of selenium compounds such as trigonal selenium. This adhesive generating layer is useful in an overcoated photoreceptor containing for example an electrically conductive substrate, overcoated with a layer of material capable of injecting holes into a layer on its surface, a hole transport layer in operative contact with the layer of hole injecting material, overcoated by a layer of the charge generating adhesive material on and in operative contact with the charge transport layer and a layer of an insulating organic resin overlaying the charge generating layer.
