Photosensitive materials for electrophotography and method for making the same.

摘要

A method for making photosensitive materials of the positive charge type which are useful in electrophotography is described. In the method, X-type and/or tau -type phthalocyanine is at least partially dissolved in a solvent along with a resin binder or in a solution of the resin binder by which good photosensitive characteristics are obtained. The photosensitive material obtained by the method may be of a single-layer or a double-layer type. A photosensitive material having an improved ozone resistance is also disclosed. The material makes use of a resin binder having vinyl phenol units therein and is resistant to ozone.
