Electrostatographic imaging members

An electrostatographic imaging member comprising at least one imaging layer capable of retaining an electrostatic latent image, a supporting substrate layer having an electrically conductive surface and an electrically conductive ground strip layer adjacent said electrostatographic imaging layer and in electrical contact with said electrically conductive surface, said electrically conductive ground strip layer comprising a film forming binder, conductive particles, crystalline silica particles dispersed in said film forming binder, and a chemical reaction product of an amino silane bi-functional chemical coupling agent with both said film forming binder and said crystalline particles, said crystalline silica particles and said amino silane bi-functional coupling agent being chemically bonded to each other through an oxygen atom by a chemical reaction between reactive hydroxyl groups chemically attached to said silica particles and reactive groups on molecules of said amino silane bi-functional coupling agent, and said amino silane bi-functional chemical coupling agent and said film forming binder being chemically bonded to each other by a chemical reaction between organo functional reactive groups on molecules of said amino silane bi-functional chemical coupling agent and reactive groups on molecules of said film forming binder.
