PURPOSE:To improve the sensitivity in the luminescent wavelength of a semiconductor laser and to environment characteristic of an image quality by specifying the mean particle size of a chlorinated aluminium phthalocyanine having a specified crystal structure as a charge generating agent to a specified range. CONSTITUTION:In a laminated type photosensitive body which mainly liminates a charge generating layer and a charge transfer layer on a conductive substrate plate, the charge generating agent is composed of the chlorinated aluminium phthalocyanine shown by the formula AlClxPcCly wherein the degree of chlori nation x+y=1.0-2.0, Pc is a phthalocyanine ring. The sensitive body has strong diffraction peaks at Bragg angles (2theta+ or -0.2) of 6.7 deg., 11.2 deg., 16.7 deg. and 25.6 deg. in a X-ray diffraction spectral, and a max. absorption of 750-850nm in a transmission absorption spectra and a mean particle size of 0.05-0.03mum. Thus, the sensitive body has the high sensitivity at the luminescent wavelength of the semiconductor laser, and the environment characteristic of the image performance mainly consisting of an electric performance and a fog is improved. |
