    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 τ -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.

    摘要： This invention relates to photosensitive materials which comprise, on a conductive support, a layer structure having at least one layer. The at least one film is made of a cured film of a dispersion of a photoconductor in a binder polymer which has recurring units of the following general formula

    wherein at least one of X₁ and X₂ is a bromine atom provided that at least one benzene ring in the units is partly or fully substituted with the bromine atom and n is an integer. The photoconductor may be X-type metal-free phthalocyanine or τ -type metal-free phthalocyanine dispersed partially in a molecular state and partially in a particulate state. Alternatively, combinations of carrier generation and carrier transport agents may be used. The layer structure is either a single-layer structure or a double-layer structure.
