Abstract

The invention provides a naphthalenetetracarboxylic ramification and an electrophotography photoreceptor. The naphthalenetetracarboxylic ramification is expressed by a formula 1. According to the formula 1, R1 and R2 are independent from each other, and are used to express a group constituted by groups formed by aryl having an amount of carbon atoms from 6 to 14, an aralkyl having an amount of carbon atoms from 7 to 20, an alkyl having an amount of carbon atoms from 1 to 8, and a naphthenic base having an amount of carbon atoms from 3 to 10, wherein one of the aryl having an amount of carbon atoms from 6 to 14 and the alkyl and the tirmethoxybenzoylurea having the amount of carbon atoms from 1 to 6 is selected. The groups can be replaced by more than one halogen atoms. At least one of R1 and R2 is provided with Halogen atoms.

Description

technical field [0001] The present invention relates to a naphthalene tetracarbodiimide derivative and an electrophotographic photoreceptor. Background technique [0002] Electrophotographic photoreceptors are used in electrophotographic image forming devices. The electrophotographic photoreceptor includes, for example, a laminate type electrophotographic photoreceptor and a single-layer type electrophotographic photoreceptor. The electrophotographic photoreceptor includes a photosensitive layer. A laminated electrophotographic photoreceptor includes, as a photosensitive layer, a charge generating layer having a charge generating function and a charge transport layer having a charge transport function. The single-layer electrophotographic photoreceptor has a single-layer photosensitive layer having a charge generating function and a charge transport function as a photosensitive layer. [0003] When an electrophotographic image forming apparatus forms an image, an image de...
