PURPOSE:To obtain a photosensitive body having highly sensitive spectral sensitivity for light ranging from visible rays to near infrared region and having superior repeatability by providing a layer contg. a polycyclic quinone compd. and a specified compd. in the layer as a charge generating material. CONSTITUTION:The title photosensitive body has a layer contg. a polycyclic quinone compd. and a compd. expressed by the formula I as a charge generating material. In the formula, Z is an atom group necessary for constituting a/an (un)substituted aromatic carbocyclic ring or (un)substituted aromatic heterocyclic ring; Y is an H atom, OH group, etc.; R1 is an H atom, (un)substituted alkyl group, etc.; Ar is a/an (un)substituted alkyl group; R2 is a/an (un)substituted alkyl group or (un)substituted aralkyl group, etc. Thus, a photosensitive body having superior characteristics in the sensitivity for white light and for semiconductor laser, as well as in the repeatability, is obtd. |
