Embodiment Construction

[0025] Hereinafter, the present invention will now be described in detail with reference to preferred embodiments thereof.

[0026] As a result of the inventor's research, it was found that it is impossible to form a The conductive layer has a high resistance, so when image formation is repeatedly performed in a low-temperature and low-humidity environment, leakage can easily occur in the electrophotographic photosensitive member.

[0027] In addition, it is known that image exposure light incident on the photosensitive layer of an electrophotographic photosensitive member may be reflected on a lower layer of the photosensitive layer (a layer existing after image exposure light passes through the photosensitive layer) or an interface with a support, and at the same time Image exposure light may be scattered in the lower layer of the photosensitive layer. As a result of research by the present inventors, it was found that in the prior art disclosed in Japanese Patent Applicati...

Abstract

The invention relates to an electrophotographic photosensitive member, a process cartridge, and an electrophotographic apparatus. Disclosed herein is an electrophotographic photosensitive member in which leakage hardly occurs even in the case of using a layer containing metal oxide particles as an electrically conductive layer in the electrophotographic photosensitive member, and which is compatible with definition in output images, the electrophotographic photosensitive member sequentially including: a support, an electrically conductive layer, and a photosensitive layer, the electrically conductive layer containing a binder material and particles represented by General Formula (1). N b2.00O5.00-XNY ......... (1) (In Formula (1), Nb is a niobium atom, O is an oxygen atom, N is a nitrogenatom, and 0.00 < Y < X <= 4.00.)

Description

technical field [0001] The present invention relates to an electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus having the same. Background technique [0002] Recently, research and development on electrophotographic photosensitive members using organic photoconductive materials (organic electrophotographic photosensitive members) are actively being carried out. [0003] An electrophotographic photosensitive member is basically composed of a support and a photosensitive layer formed on the support. However, in practice, various layers are often provided on the support in order to cover surface defects of the support, protect the photosensitive layer from electrical damage, improve charging and improve charge injection inhibition from the support to the photosensitive layer, etc. between the photosensitive layer. [0004] Among the layers provided between the support and the photosensitive layer, a layer containing metal oxide ...
