PURPOSE:To obtain an electrophotographic sensitive body having high sensitivity to light of >=800nm long wavelengths without requiring treatment with a solvent by using specified bromogallium phthalocyanine as the material of the charge generating layer of a two-layered separated function type sensitive body. CONSTITUTION:Bromogallium phthalocyanine represented by formula I (where Me is Ga, and X is Br) is used as the material of a charge generating layer. Bromogallium phthalocyanine GaBrPc is synthesized by adding 7.0g o-phthalodinitrile and 3.5g gallium bromide of 99.999% purity to quinoline in a flask and bringing them into a reaction under reflux. A charge generating layer 12 of GaBrPc having 0.2mum thickness is formed on an electrically conductive substrate 11 by resistance heating and vapor deposition. The layer 12 is exposed to THF vapor and coated with polyvinylcarbazole resin for electrophotography dissolved in THF, and a charge transferring layer 13 is formed by well removing the THF by drying to manufacture a sensitive body. |
