    • A wet-developing electrography photoreceptor which has excellent durability and solvent resistance and is manufactured stably by using specific physical indices of an electron transporting agent and a binding resin is provided. A wet-developing image forming device is also provided. The wet-developing electrography photoreceptor comprises on a conductive base a photosensitive layer containing at least a charge generating agent, an electron transporting agent, a hole transporting agent, and a binding resin. In such a wet-developing electrography photoreceptor and a wet-developing image forming device used in the wet-developing image forming device, the inorganic value/organic value (I/O value) of the electron transporting agent is 0.60 or more, and the inorganic value/organic value (I/O value) of the binding resin is 0.37 or more. Alternatively the molecular weight of the electron transporting agent is 600 or more and the inorganic value/organic value (I/O value) of the binding resin is 0.37 or more.
    • 提供具有优异的耐久性和耐溶剂性并且通过使用电子传输剂和粘合树脂的特定物理指数稳定地制造的湿显影电光学感光体。 还提供了湿显影图像形成装置。 湿显影电光学感光体在导电基底上包含至少含有电荷产生剂,电子传输剂,空穴传输剂和粘合树脂的光敏层。 在这样的湿式显影型图像形成装置中使用的湿式显影型电子照相感光体和湿式显影型图像形成装置中,电子传输剂的无机值/有机值(I / O值)为0.60以上, 粘合树脂的无机值/有机值(I / O值)为0.37以上。 或者,电子传输剂的分子量为600以上,并且粘合树脂的无机值/有机值(I / O值)为0.37以上。
