Title:
ヒドロキシガリウムフタロシアニン結晶、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
Document Type and Number:
Japanese Patent JP6541447
Kind Code:
B2
Abstract:
The present invention provides a novel hydroxygallium phthalocyanine crystal and an electrophotographic photosensitive member capable of outputting an image with few failures due to a ghost phenomenon not only in normal-temperature, normal-humidity environments but also even in low-temperature, low-humidity environments. The hydroxygallium phthalocyanine crystal has peaks at Bragg angles 2θ±0.2° of 7.5°, 9.9°, 25.2°, and 28.3° as determined by X-ray diffraction with Cu Kα radiation. The intensity of the peak at a Bragg angle 2θ±0.2° of 9.9° is higher than the intensity of the peak at a Bragg angle 2θ±0.2° of 7.5°.
