Electrophotographic sensitive body

Abstract

Abstract PURPOSE:To form an electrophotographic sensitive body high in sensitivity to long wavelength light and superior in chargeability by using specified metal- free phthalocyanine having a longer axis diameter specified in length as an electrostatic charge generating substance. CONSTITUTION:An electrophotographic sensitive body is obtained by laminating on a conductive substrate a <= about 20mum thick charge generating layer contg. (A) a metal-free phthalocyanine compd. selected from tau, tau', eta, and eta' types and having a longer axis of 1-5mum diameter, and a 5-100mum thick charge transfer layer contg. (B) a charge transfer substance, preferably, a positive hole transfer type substance having an ionization potential of <= about 6.6eV.
