Title:
ELECTROPHOTOGRAPHIC RECEPTOR
Document Type and Number:
Japanese Patent JPS5846347
Kind Code:
A
Abstract:

PURPOSE: To obtain a photoreceptor having high sensitivity to a light in a region from visible light to a semiconductor laser light, and high printing resistance, by forming 2 photoconductive layers composed of a first vapor deposited squaric acid methine dye layer and a second Se-Te or Se-Te-Cl layer on a conductive substrate.

CONSTITUTION: A squaric acid methine dye having the shown formula is vapor deposited on a conductive substrate in vacuum to form a first photoconductive layer, and on this layer a second photoconductive layer is formed by vapor depositing Se-Te containing 6W12wt% Te or Se-Te-Cl containing 6W12wt% Te and 15W100ppm Cl. The photoreceptor thus obtained has strong adhesion between each layer, photosensitivity ranging from visible light to 850nm, uniform photoconductive layers, and superior printing resistance.
