Abstract
An organic photoconductive material which is useful as a raw material compound for a variety of functional materials and makes it possible to implement an electrophotoconductor which is excellent in terms of the charge transporting performance, excellent in terms of dissolution in solvents and compatibility with resins, and excellent in terms of both the electrical properties and durability is provided. An example is an asymmetric bishydroxy compound which can be represented by the following structural formula (1aa). This compound is contained in a charge transforming layeror a surface protective layerof an electrophotoconductor. As a result, an electrophotoconductorwhich is excellent in terms of the electrical properties and durability and can stably form high quality images without image defects such as black dots can be implemented.
