Abstract
The disclosure is concerned with a photoconductive member useful for electrophotography wherein a charge generating layer containing a new metal-free phthalocyanine and a charge transport layer containing a nonionic compound of styrylic or oxazol dye base. The photosensitive member exhibits a high sensitivity to light having a long wavelength and therefore, it is properly used as photosensitive member for printers using semiconductor lasers.
