Problems solved by technology

However, the surface layer containing this material has a lower hardness compared to the surface layer formed using film formation in the gas phase
As a result, when the surface of the photoreceptor is damaged or worn over time, surface adhesion increases and toner adheres to the surface of the photoreceptor, causing a problem of shortening the life of the photoreceptor

Embodiment 1

[0252] First, an organic photoreceptor in which an undercoat layer, a charge generating layer, and a charge transporting layer are sequentially stacked on an aluminum substrate was manufactured in the following procedure.

[0253] Formation of base coat

[0254] By stirring and mixing 20 parts by weight of a zirconium compound (trade name: ORGATICS ZC540, manufactured by Matsumoto Chemical Industry Co., Ltd.), 2.5 parts by weight of a silane compound (trade name: A1100, manufactured by Nippon Unicar Company Limited), 10 parts by weight Parts of polyvinyl butyral resin (trade name: S-LEC BM-S, manufactured by Sekisui Chemical Co., Ltd.) and 45 parts by weight of butanol are coated on the surface of an aluminum substrate with an outer diameter of 84 mm, And heating and drying at a temperature of 150° C. for 10 minutes, thereby forming an undercoat layer having a thickness of 1.0 μm.

[0255] Formation of charge generation layer

[0256] Next, by mixing 1 part by weight of chlo...

Embodiment 2

[0303] A photoreceptor (2) was obtained in the same manner as in Example 1, except that, when the electrophotographic photoreceptor of Example 1 was produced, a mixed gas of nitrogen, helium, and oxygen introduced through the gas inlet 20 The amount of the gas was changed to about 200 sccm (nitrogen gas 100 sccm, helium gas 100 sccm and oxygen gas 1 sccm) to form a surface layer.

[0304] In addition, evaluation was performed in the same manner except that, in the evaluation of Example 1, the photoreceptor (2) was used instead of the photoreceptor (1). The infrared absorption spectrum of the surface layer of the photoreceptor (2) is shown in FIG. 9 .

[0305] In Table 1 the results including the analysis of the surface layer are shown.

Embodiment 3

[0307] A photoreceptor (3) was obtained in the same manner as in Example 1, except that, in manufacturing the electrophotographic photoreceptor of Example 1, by changing the mixed gas introduced through the gas inlet 20 to nitrogen, helium, A mixed gas of hydrogen and oxygen was introduced into about 450 sccm (100 sccm of nitrogen, 150 sccm of helium, 200 sccm of hydrogen, and 0.1 sccm of oxygen) to form a surface layer.

[0308] In addition, the evaluation was performed in the same manner except that, in the evaluation of Example 1, the photoreceptor (3) was used instead of the photoreceptor (1). The infrared absorption spectrum of the surface layer of the photoreceptor (3) is shown in FIG. 10 .

[0309] In Table 1 the results including the analysis of the surface layer are shown.

Abstract

An electrophotographic photoreceptor comprising a photosensitive layer and a surface layer laminated on a conductive substrate in this order, wherein the surface layer contains a group 13 element and oxygen, and absorption peak intensities showing bonds other than a bond between the group 13 element and oxygen are 0.1 times or less of an absorption peak intensity showing a bond between the group 13 element and oxygen in an infrared absorption spectrum in a range of 4000 cm<-1 >to 400 cm<-1>, is provided.

Description

technical field [0001] The present invention relates to an electrophotographic photoreceptor used in copiers and the like to form an image by an electrophotographic method, a process cartridge and an image forming apparatus using the electrophotographic photoreceptor. Background technique [0002] Recently, electrophotography is widely used in copiers, printers, and the like. An electrophotographic photoreceptor (hereinafter also referred to as a "photoreceptor") used in an image forming device utilizing such an electrophotography method is subjected to various contacts and stresses in the device, resulting in deterioration. However, on the other hand, along with digitization and colorization of the imaging device, high reliability of the imaging device is desired. [0003] For example, if the charging process of the photoreceptor is mentioned, there are problems as follows. First, in the non-contact charging method, discharge products adhere to the photoreceptor, and imag...
