Abstract
Official abstract text for this publication.
An electrophotographic photoreceptor includes a substrate, an undercoat layer overlying the substrate, and a photosensitive layer overlying the undercoat layer. The undercoat layer includes a binder resin, a metal oxide particle and a compound having a thiol group.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrophotographic photoreceptor, comprising: a substrate; an undercoat layer overlying the substrate; and a charge generation layer and a charge transport layer overlying the undercoat layer, wherein the undercoat layer comprises a binder resin, a metal oxide particle and a compound having a thiol group selected from the group consisting of 1,3,5-tris(3-mercaptobutyryloxyethyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione, 1,4-bis(3-mercaptobutyryloxy) butane, and N-dodecylmercaptane. 2. The electrophotographic photoreceptor of claim 1 , wherein the compound having a thiol group is a chain-transfer agent having a thiol group. 3. The electrophotographic photoreceptor of claim 1 , wherein the metal oxide particle is a zinc oxide particle. 4. The electrophotographic photoreceptor of claim 1 , wherein the compound having thiol group has at least two thiol groups. 5. The electrophotographic photoreceptor of claim 1 , wherein the undercoat layer has an average thickness of from 5 μm to 30 μm. 6. An image forming apparatus, comprising: the electrophotographic photoreceptor according to claim 1 ; a charger to charge the surface of the electrophotographic photoreceptor; an irradiator to irradiate the surface of the electrophotographic photoreceptor to form an electrostatic latent image thereon; an image developer to develop the electrostatic latent image with a toner to form a visible image on the electrophotographic photoreceptor; and a transferer to transfer the visible image onto a recording medium. 7. A process cartridge, comprising: the electrophotographic photoreceptor according to claim 1 ; and at least one of a charger to charge the surface of the electrophotographic photoreceptor, an irradiator to irradiate the charged surface of the electrophotographic photoreceptor to form an electrostatic latent image thereon, an image developer to develop the electrostatic latent image with a toner to form a visible image on the electrophotographic photoreceptor, and a transferer to transfer the visible image onto a recording medium.
