摘要： A flexible imaging member which does not require the use of an anti-curl back coating is disclosed herein. The flexible imaging member has a layer comprising two charge transport molecules dispersed in a film-forming polymer binder and an overcoat layer. The first charge transport molecule is a biphenyl amine, terphenyl diamine, or bis(triarylamine) stilbene. The second charge transport molecule is a bis(triarylamine), tri-p-tolylamine, or triphenylamine. The weight ratio of second charge transport molecule to first charge transport molecule is from about 90:10 to about 66:34. Trifluoro acetic acid is also added to the layer containing the charge transport material.

摘要： An imaging member has a crosslinked overcoat layer which holds fluorinated nanoparticles. The overcoat layer is formed from an overcoat solution comprising a polymer binder; a hole transport molecule; fluorinated nanoparticles; a fluorinated surfactant; a crosslinking agent; and a free radical initiator. The overcoat layer provides excellent wear resistance at a low cost.

摘要： An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
