[0146] (Examples 1-9, Comparative Examples 1-6)

[0147] The conductive endless belts of the respective examples and comparative examples were produced according to the formulations shown in each of the following Tables 6 to 8. Specifically, by using a twin-screw kneader to melt and knead each of the compounding components with a base shown in each table, and extrude the obtained kneaded product using a ring die, a product having an inner diameter of 220 mm was obtained. , the base layer 101 having a thickness of 100 μm and a width of 250 mm. Then, on the base layer 101, a solvent coating solution of a resin layer prepared using the compounding materials shown in the tables and using methyl ethyl ketone as a solvent was spray-coated so that the film thickness after drying was 2 μm. While rotating the coated tape 100, using a UNICURE UVH-0252C device manufactured by Ushio Inc., with an illuminance of 400 mW and a cumulative light intensity of 1000 mJ / cm 2 Under certain condit...

Abstract

Provided at lower cost is an electroconductive endless belt which is even and has no local unevenness and with which satisfactory images are obtained. The electroconductive endless belt (100) is an endless belt for use in an image-forming device and has a multilayer structure which comprises a base layer (101) and a cured resin layer (102) in this order from inside. The base layer (101) comprises a thermoplastic resin, and the cured resin layer (102) comprises an ultraviolet-curable resin, an ionically conductive agent, at least 1,4-butanediol acrylate or polytetramethylene glycol acrylate, and a polymer having ethylene oxide, the content of the ionically conductive agent being 0.5-5 parts by mass per 100 parts by mass of the total content of the ultraviolet-curable resin, at least 1,4-butanediol acrylate or polytetramethylene glycol acrylate, and polymer having ethylene oxide.

Description

technical field [0001] The present invention relates to a conductive endless belt (hereinafter also simply referred to as a "belt") used for transferring a toner image to a recording medium such as paper during electrostatic recording in electrophotographic devices such as copiers and printers, and electrostatic recording devices. ), wherein the toner image is formed by supplying a developer to the surface of an image forming body such as a latent image holder holding an electrostatic latent image on its surface. Background technique [0002] Conventionally, in the electrostatic recording process of copiers, printers, etc., the following method is used: first, the surface of the photoreceptor (latent image holder) is uniformly charged, and an image is projected on the photoreceptor by an optical system to eliminate the part where the light is irradiated. to form an electrostatic latent image, and then supply toner to the electrostatic latent image, form a toner image by elec...
