Abstract:
1. A monolayer type photoconductor, comprising a base body and a single photo sensitive layer formed on the base body, the single photo sensitive layer containing a charge generating agent, a hole transfer agent, an electron transfer agent and a binding resin, wherein the maximum absorption wavelength (λ wherein the maximum absorption wavelength (λ wherein the charge generating agent is a titanyl phthalocyanine crystal having maximum peaks at Bragg angles 2θ of 9.5°±0.2° and 27.2°±0.2°, in a CuKα X-ray diffraction spectrum, wherein the titanyl phthalocyanine crystal has two peaks in a range of 50 to 400° C. by differential scanning calorimetry, with one peak due to vaporization of adsorbed water in the range of 50 to 270° C., and one peak in the range of 270 to 400° C., and wherein the titanyl phthalocyanine crystal having an absorbance of light at a wavelength of 400 nm, as determined as a solution obtained by suspending 1.25 parts by weight of the titanyl phthalocyanine crystal in 100 parts by weight of a mixed solvent of methanol and N,N-dimethylformamide (methanol:N,N-dimethylformamide=1:1 (by weight)) and filtering the suspension, in the range of 0.01 to 0.08 is used as the titanyl phthalocyanine crystal, and
