    • An electrophotographic imaging member fabricated by forming on a charge generating layer a first coating including charge transporting molecules dispersed in a solution of a first polymer binder dissolved in a first solvent, drying the coating to remove the solvent to form a substantially dry charge transport layer, forming on the charge transport layer a second coating including charge transporting molecules and a chemical stabilizer additive selected from the group consisting of a nitrone, isobenzofuran, hydroxyaromatic compound and mixtures thereof molecularly dispersed in an electrically inactive second polymer binder in a solution of a second polymer binder dissolved in a second solvent, the first polymer binder being insoluble in the second solvent, and drying the second coating to remove the second solvent to form a substantially dry overcoat layer. This electrophotographic imaging member may be utilized in an electrophotographic imaging process.
    • 由电荷产生层上形成第一涂层,包括间歇输送分散在第一溶剂中溶解第一聚合物粘合剂的溶液中的分子,干燥该涂层而制造的电子照相成像元件,以除去溶剂,形成基本上干燥的电荷输送层, 形成电荷输送层上的第二涂层,包括间歇传输分子和选自硝酮,异苯并呋喃,羟基芳族化合物的及其混合物分子分散在上电惰性第二聚合物粘合剂中的第二聚合物的溶液中选择的化学稳定剂添加剂 在第二溶剂中溶解的粘合剂,所述第一聚合物粘合剂是在第二溶剂中是不溶的,并干燥该第二涂层以除去所述第二溶剂以形成基本上干燥的外涂层。 该电照相成像元件可以在电子照相成像过程中利用英寸
