    摘要： An object of the present invention is to provide an electrophotographic photosensitive body having improved electrophotographic characteristics such as sensitivity and residual potential and also having excellent durability. The present invention provides an electrophotographic photosensitive body having a layer containing at least one specific p-terphenyl compound and at least one polycarbonate resin represented by the general formula (I): in a mass ratio of the p-terphenyl compound to the polycarbonate resin within the range of 2:8 to 7:3.

    摘要： An object of the invention is to provide: a p-terphenyl compound mixture useful as a charge-transporting agent which has improved solubility in organic solvents to thereby diminish a cracking phenomenon, which poses problems concerning photoreceptor characteristics, and can realize an electrophotographic photoreceptor having high sensitivity and high durability; and an electrophotographic photoreceptor employing the compound mixture. The invention relates to: a p-terphenyl compound mixture which includes two symmetric p-terphenyl compounds respectively represented by the following general formula (1) and general formula (2) and an asymmetric p-terphenyl compound represented by the following general formula (3) which has both a group of substituents of the compound represented by general formula (1) and a group of substituents of the compound represented by general formula (2); and an electrophotographic photoreceptor containing the compound mixture.
