    • An object of the present invention is to provide a charge transport material and an electrophotographic photoreceptor using the charge transport material, the charge transport material sufficiently satisfying characteristics conventionally desired for a charge transport material for an electrophotographic photoreceptor, specifically, the charge transport material having a good solubility in a binder polymer, allowing formation of a stable and high-concentration organic thin film therefrom, and having a high carrier mobility. To achieve the object, the present invention provides a tris(4-styrylphenyl)amine derivative represented by the following general formula (1): wherein R1 represents a methyl group or methoxy group, and R2 represents a hydrogen atom, methyl group, or methoxy group, provided that a case where R1 and R2 are a methyl group and R2 is at the meta-position is excluded; wherein 50% or more of geometrical isomers have three double bonds which are all trans.
    • 本发明的目的是提供一种使用电荷输送材料的电荷输送材料和电子照相感光体,电荷输送材料充分满足电子照相感光体的电荷输送材料通常所要求的特性,具体地说,具有 在粘合剂聚合物中具有良好的溶解性,从而形成稳定且高浓度的有机薄膜,并具有高载流子迁移率。 为了达到上述目的,本发明提供由以下通式(1)表示的三(4-苯乙烯基苯基)胺衍生物:其中R1表示甲基或甲氧基,R2表示氢原子,甲基或甲氧基 只要R1和R2为甲基,R2为间位的情况除外; 其中50%或更多的几何异构体具有全部反式的三个双键。
