Abstract:
An electrophotographic photosensitive member includes a support and a photosensitive layer in this order. The photosensitive layer contains a chlorogallium phthalocyanine crystal. The chlorogallium phthalocyanine crystal has one or more peaks in each of a wavelength range of 646 nm or more and 668 nm or less and a wavelength range of 782 nm or more and 809 nm or less in an absorption spectrum. When a peak with a maximum absorbance among the peaks in the wavelength range of 646 nm or more and 668 nm or less is assumed to be a first peak and a peak with a maximum absorbance among the peaks in the wavelength range of 782 nm or more and 809 nm or less is assumed to be a second peak, an absorbance of the first peak is larger than an absorbance of the second peak.

Abstract:
The invention has for its object to provide a water-soluble phthalocyanine dye unlikely to lose its own properties even upon dissolved in a concentration as high as 10−5 M.The inventive water-soluble phthalocyanine dye is characterized by having a sulfuric acid group or groups as an axial ligand or ligands of an antimony/phthalocyanine complex. The sulfuric acid group or groups have been introduced by replacing a part or the whole of hydroxyl groups in the starting material with a sulfuric acid group or groups.
