Embodiment 1

[0299] 100 parts by mass of zinc oxide (manufactured by Teika Corporation, average particle size: 70 nm, specific surface area: 15 m 2 / g) was mixed with 500 parts by mass of tetrahydrofuran under stirring; 1.25 parts by mass of a silane coupling agent (KBM603: manufactured by Shin-Etsu Chemical) was further added; and the mixture was then stirred for 2 hours. Then, tetrahydrofuran was distilled off under reduced pressure, and the resulting mixture was baked at 120° C. for 3 hours to obtain a zinc oxide pigment whose surface was treated with a silane coupling agent.

[0300] 100 parts by mass of surface-treated zinc oxide and 500 parts by mass of tetrahydrofuran were mixed under stirring, a solution obtained by dissolving 1 part by mass of alizarin in 50 parts by mass of tetrahydrofuran was added, and the mixture was stirred at 50° C. for 5 hours. Then, the alizarin-attached zinc oxide was separated by vacuum filtration under reduced pressure, and dried under reduced pressure ...

Embodiment 2-4

[0308] An electrophotographic photoreceptor was prepared in the same manner as in Example 1, except that the acceptor compound attached to the zinc oxide surface-treated with a silane coupling agent in Example 1 was replaced with the compound shown in Table 1. , and evaluate its performance. The results are shown in Table 11.

Abstract

The present invention provides an electrophotographic photoreceptor. An electrophotographic photoreceptor including at least an undercoat layer and a photosensitive layer on a conductive substrate, in which the undercoat layer includes metal oxide fine particles to which an electron acceptor compound is attached.

Description

technical field [0001] The present invention relates to an electrophotographic photoreceptor suitable for electrophotographic image formation, an electrophotographic cartridge, and an electrophotographic device. Background technique [0002] Electrophotography capable of achieving high speed and high printing quality has been applied to electrophotographic devices such as copiers or laser printers. [0003] The electrophotographic photoreceptor used in this electrophotographic device is mainly an organic electrophotographic photoreceptor using an organic photoconductive material, and the structure of the electrophotographic photoreceptor can be changed to become a function-separated type electrophotographic photoreceptor, thereby To improve its performance, the electrophotographic photoreceptor of the function-separated type has a charge transport material and a charge generation material dispersed in each layer. [0004] Currently, this function-separated type electrophoto...
