摘要:
Disclosed is an electrophotographic photoreceptor which is superior in sensitivity to light of longer wavelength region with good stability of the sensitivity and is suitable for formation of high quality color image by scanning exposure with laser beam. This photoreceptor comprises an electroconductive support and, provided thereon, a photosensitive layer containing a titanium dioxide sensitive to light of longer wavelengths which is obtained by treating the surface of titanium dioxide particles with a mineral acid and then supporting on the surface of the particles a cyanine dye sensitizer and a hydrophobic organic compound. The mineral acid is preferably hydrofluoric acid and the hydrophobic organic compound is preferably aromatic or aliphatic organic acid and acid anhydride thereof.
摘要:
