Title:
ポルフィリナト亜鉛化合物の結晶
Document Type and Number:
Japanese Patent JP4604106
Kind Code:
B2
Abstract:
An electrophotographic photosensitive member having a sensitivity to a short semiconductor laser light in a wavelength range of 380 - 500 nm is provided by incorporating a specific porphyrin compound in a photosensitive layer. The porphyrin compound is characterized by having a heterocyclic substituent, preferably 4 heterocyclic substituents each of a pyridyl group. The porphyrin compound includes a 5,10,15,20-tetrapyridyl-21H,23H-porphyrinato-zinc compound having a novel crystal form characterized by certain peaks in a CuK alpha -characteristic X-ray diffraction pattern.
