Abstract
The α-titanylphthalocyanine dispersed in resinous solution with a grinding system formed
microcrystals of high orientation.
The dispersion film showed strong absorption in the infrared region (λmax=830 nm) same as the case of a vacuum deposition film followed by solvent treatment. Electrophotographic properties were measured of multilayered photoreceptors incorporationg α-TiOPc dispersed film as CGL and a hydrazone compound layer as CTL. The photoreceptor showed high sensitivity in the wavelengths of LED (E1/2=0.54 μJ/cm2 at 660 nm) and laser diode (E1/2=0.36 μJ/cm2 at 780 nm) and was suggested to have enough durability in use of those printers in according to performance in the tests for environmental conditions and cyclic stability.
