Title:
電子写真感光体、プロセスカートリッジ及び電子写真装置、並びに、クロロガリウムフタロシアニン結晶及びその製造方法
Document Type and Number:
Japanese Patent JP6632323
Kind Code:
B2
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.
