Zusammenfassung: | PURPOSE:To obtain the titled body having less tendency for generating crystallization and inhomogeneity in an electrostatic charge transfer layer of the titled body by incorporating a polycarbonate resin contg. bisphenol A and a specific dioxy compd. as a diol component, and a specific benzidine compd. in the electrostatic charge transfer layer of the titled body. CONSTITUTION:The electrostatic charge transfer layer contains the polycarbonate resin contg. bisphenol A shown by formula I and the dioxy compd. shown by formula II, as the diol component, and the benzidine compd. shown by formula III, in the electrostatic charge transfer layer. The compounding ratio of bisphenol A shown by formula I and the dioxy compd. shown by formula II in the polycarbonate resin is effectively a range of (1:19)-(19:1), preferably, (3:17)-(1:1). The polycarbonate resin has preferably a mol.wt. of 50,000-110,000. The compounding ratio of the benzidine compd. shown by formula III contd. in the electrostatic charge transfer layer is preferably 25-75wt%. |
