Problems solved by technology

[0008] However, the triphenylamine derivatives (HTM-A~B) represented by formulas (a)~(b) are methyl or methoxy groups due to the substituents on the para-position of the arylamine groups, so the solubility and Insufficient compatibility with binder resin
[0009] From this, it was found that when such a triphenylamine derivative is used as a hole-transporting agent for an electrophotographic photoreceptor, crystallization and poor dispersion in the photosensitive layer tend to occur, so it is difficult to obtain desired sensitivity characteristics.

Description

technical field [0001] The present invention relates to a triphenylamine derivative, a method for producing the same, and an electrophotographic photoreceptor. In particular, it relates to a triphenylamine derivative which has excellent solubility in solvents and compatibility with binder resins, and is useful for effectively improving sensitivity characteristics by being used as a hole-transporting agent for electrophotographic photoreceptors, and its Manufacturing method and electrophotographic photoreceptor. Background technique [0002] Currently, an organic photoreceptor (OPC) composed of a binder resin (binder resin), a charge generating agent, a charge transporting agent (hole transporting agent, electron transporting agent), etc. photoreceptor. Compared with conventional inorganic photoreceptors, such an organic photoreceptor is easier to manufacture and has a variety of options for photoreceptor materials, so it has the advantage of a greater degree of freedom in ...
