Abstract
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.
