Abstract: A photoconductor that includes a first layer, a supporting substrate thereover, a photogenerating layer, and at least one charge transport layer of at least one charge transport component, and wherein the first layer is in contact with the supporting substrate on the reverse side thereof, and which first layer is comprised of a crosslinked mixture of a glycoluril resin and a self crosslinking acrylic resin.
Abstract: An emulsion aggregation toner composition includes toner particles including: an unsaturated polymeric resin, such as amorphous resins, crystalline resins, and combinations thereof; an optional colorant; an optional wax; an optional coagulant; and an IR absorber. The use of an IR absorber may permit formation of color toners that have uniform gloss and crease properties, i.e., the IR absorbers may prevent gloss and crease differences between color and black toners.
