電子写真感光体、画像形成装置及びプロセスカートリッジ
Document Type and Number:
Japanese Patent JP6680257
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that can improve voltage resistance and filming resistance while reducing the occurrence of exposure memory.SOLUTION: An electrophotographic photoreceptor 1 comprises: a conductive substrate 2; and a photosensitive layer 3. The photosensitive layer 3 is a single layer and contains a charge generating agent, a hole transport agent, an electron transport agent, a binder resin, and fluorine resin particles. The charge generating agent contains titanyl phthalocyanine having a main peak at a Bragg angle (2θ±0.2°) of 27.2° in a CuKα characteristic X-ray diffraction spectrum. When the absorbance to light with a wavelength of 780 nm in the photosensitive layer is A, the thickness of the photosensitive layer is T(μm), and the concentration of titanyl phthalocyanine in the photosensitive layer is W(mass%), the following formula (1) is satisfied. (1) 0.018≤A/(T W)≤0.061.SELECTED DRAWING: Figure 1
