The present invention provides an electrophotographic element. The element has a charge generation layer including binder and, dispersed in the binder, a physical mixture of (1) a high speed cocrystallized mixture of TiOPc and TiOFPc having a first intensity peak at 7.4 with respect to X-rays characteristic of Cu Kα at a wavelength of 1.541 Å of the Bragg angle 2θ and a second intensity peak at 28.6°±0.2°, and (2) a low speed phthalocyanine pigment.
