Abstract
An organic photoreceptor having a photosensitive layer on a conductive support is disclosed, in which the photosensitive layer contains a pigment containing an adduct of titanyl phthalocyanine and at least either of (2R,3R)-2,3-butanediol and (2S,3S)-2,3-butanediol, the spectrum of the photosensitive layer has the absorption maximum value in the region of 750 to 780 nm, and the ratio of the absorbance at 780 nm (Abs 780) to the absorbance at 750 nm (Abs 750) (Abs 780/Abs 750, a value obtained by correcting the absorbance at 1000 nm as 0) is 0.6 to 1.0.
Claims8
An electrophotographic photoreceptor having a photosensitive layer on a conductive support, wherein
- the photosensitive layer comprises a pigment containing an adduct of titanyl phthalocyanine and at least either of (2R,3R)-2,3-butanediol and (2S,3S)-2,3-butanediol,
- a spectrum of the photosensitive layer has an absorption maximum value in a region of 750 to 780 nm, and
- a ratio of Abs 780/Abs 750, a value obtained by correcting the absorbance at 1000 nm as 0, is 0.6 to 1.0, wherein Abs 780 is an absorbance at 780 nm and Abs 750 is an absorbance at 750 nm of the photosensitive layer.
