ABSTRACT:
The object of the invention is to provide an electro-photographic photoreceptor which has high sensitivity to long wavelength light to form a less defective image and exhibits a sufficient electrical charging property at the first rotation of the receptor to rapidly form an image. The electro-photographic photoreceptor is constructed by laminating an intermediate layer, a charge generation layer and a charge transport layer in order on a conductive support. The intermediate layer contains an adhesive resin, a carboxylic acid salt of the following structural formula (I), and titanium oxide. The content of the carboxylic acid salt is in a range of 0.5-5 weight % and that of titanium oxide in 10-50 weight % for the total amount of the intermediate layer.
