    • A multi-active electrophotographic charge generation element comprises a conductive support, a charge generation layer (CGL) disposed on the conductive support, and a charge transport layer (CTL) disposed on the charge generation layer. The charge generation layer (CGL) includes a charge-generation material comprising an aggregated or crystalline form of a first dye or pigment and a first polymeric binder. The charge transport layer (CTL) comprises at least one charge-transport agent, a second dye or pigment having absorption in a selected spectral region that at least partially overlaps the absorption of a dissolved non-aggregated or non-crystalline form of the first dye or pigment, and a second polymeric binder. The second dye or pigment in the charge transport layer absorbs radiation in the selected spectral region that is incident on the charge transport layer, thereby shielding the charge generation layer from that radiation and mitigating visible radiation-induced photofatigue.
    • 多有源电子照相电荷电荷产生元件包括导电支撑体，设置在导电支撑体上的电荷产生层（CGL）和设置在电荷产生层上的电荷传输层（CTL）。 电荷产生层（CGL）包括电荷产生材料，其包含聚集或结晶形式的第一染料或颜料和第一聚合物粘合剂。 电荷传输层（CTL）包括至少一种电荷传输剂，在所选光谱区域中具有吸收的第二染料或颜料，其至少部分地与第一染料的溶解非聚集或非结晶形式的吸收重叠 或颜料，和第二聚合物粘合剂。 电荷传输层中的第二种染料或颜料吸收入射在电荷传输层上的所选光谱区域中的辐射，从而屏蔽电荷产生层免受该辐射并减轻可见光辐射诱导的光致发光。
