ABSTRACT:
An electrophotographic element and a preparation method. The element has a charge generation layer including binder and, dispersed in the binder, a physical mixture of: a high speed titanyl fluorophthalocyanine and a low speed titanyl fluorophthalocyanine. The high speed titanyl fluorophthalocyanine has a first intensity peak with respect to X-rays characteristic of Cu K.alpha. at a wavelength of 1.541 .ANG. of the Bragg angle 2.theta. at 27.degree..+-.0.2.degree. and a second intensity peak at 7.3.degree..+-.0.2.degree.. The second peak has an intensity relative to the first peak of less than 60 percent. The low speed titanyl fluorophthalocyanine has a first intensity peak with respect to X-rays characteristic of Cu K.alpha. at a wavelength of 1.541 .ANG. of the Bragg angle 2.theta. at 6.7.degree..+-.0.2.degree. and a second intensity peak at 23.7.degree..+-.0.2. The second peak has an intensity relative to the first peak of less than 50 percent.
