Abstract
A photoreceptor for electrophotography containing a titanyl phthalocyanine compound which has major peaks in terms of Bragg's 2.theta. angle to the CuK.alpha. characteristic X-ray (wavelength at 1.541 .ANG.) at least at 9.4.+-.0.2 degrees, 11.7.+-.0.2 degrees, 11.7.+-.0.2 degrees, 15.0.+-.0.2 degrees, 23.5.+-.0.2 degrees, 24.1.+-.0.2 degrees and 27.3.+-.0.2 degrees is disclosed.
Claims4
A photoreceptor for electrophotography comprising a titanyl phthalocyanine compound which has major peaks in terms of Bragg's 2.theta.angle to the CuK.alpha. characteristic X-ray wavelength at 1.541 .ANG. at least at 9.5.+-.0.2 degrees, 11.7.+-.0.2 degrees, 15.0.+-.0.2 degrees, 23.5.+-.0.2 degrees, 24.1.+-.0.2 degrees and 27.3.+-.0.2 degrees.
A photoreceptor for electrophotography comprising an electroconductive support and, provided thereon, a photosensitive layer containing a titanyl phthalocyanine compound which has major peaks in terms of Bragg's 2.theta. angle to the CuK.alpha. characteristic X-ray wavelength at 1.541 .ANG.at least at 9.5.+-.0.2 degrees, 11.7 .+-.0.2 degrees, 15.0.+-.0.2 degrees, 23.5.+-.0.2 degrees, 24.1.+-.0.2 degrees and 27.3.+-.0.2 degrees as a carrier generating substance, and a compound having formula I as a carrier transporting substance;
