摘要： Electrophotographic photosensitive material comprising an electroconductive substrate and a layer of a photoconductive composition composed of a dispersion of a charge generating pigment in a charge transporting medium, which is formed on the electroconductive substrate, wherein said photoconductive composition contains an N,N-di-substituted-carbamic acid salt in an amount of 20 to 200% by weight based on the charge generating pigment. This electrophotographic electrophotosensitive material has excellent ozone resistance and shows a high initial charge retention ratio and sensitivity retention ratio when the cycle of charging and light exposure is repeated many times.
