Problems solved by technology

[0016] However, in the contact charging method, since the discharge area is narrow, the charging ability is insufficient compared with the non-contact charging method.
Therefore, there is a problem that the potential of the surface of the electrophotographic photoreceptor is not easily stabilized, and transfer storage is likely to occur.
[0017] In this way, in an image forming apparatus equipped with a charging part of the contact charging method, transfer memory is very likely to occur when a positively charged single-layer electrophotographic photoreceptor is used. However, even if the triarylamine derivative disclosed in Patent Document 1 is used as the hole Transport agent, and it is not easy to inhibit the generation of transfer storage

Abstract

The invention relates to a triarylamine derivative, a positive charging single-layer electrophotographic photoconductor and an image-forming apparatus having contact charged part. The triarylamine derivative of the invention is expressed by a formula (1). According to the invention, the aforementioned triarylamine derivative is provided to the electrophotographic photoconductor which does not generate image exposure storage. Besides, the image-forming apparatus of the invention can continuously provide nice images because the electrophotographic photoconductor is provided as an image carrier.

Description

technical field [0001] The present invention relates to a triarylamine derivative, an electrophotographic photoreceptor using the triarylamine as a hole transport agent, and an image forming apparatus provided with the electrophotographic photoreceptor as an image carrier. Background technique [0002] The electrophotographic photoreceptor included in the electrophotographic image forming device includes an inorganic photoreceptor and an organic photoreceptor. The inorganic photoreceptor has a photosensitive layer composed of inorganic materials such as selenium and amorphous silicon. A photosensitive layer composed of organic materials such as resins, charge generators, and charge transport agents. Furthermore, among these photoreceptors, organic photoreceptors are widely used because they are easier to manufacture than inorganic photoreceptors, can select a material for a photosensitive layer from a wider range of materials, and have a high degree of freedom in design. ...
