no. 1 approach

[0045] The first embodiment is an electrophotographic photoreceptor having a photosensitive layer including a binder resin, an electron transport agent, and a charge generating agent, wherein the electron transport agent includes, as the electron transport agent, represented by the above general formula (1). compound.

[0046] Here, the electrophotographic photoreceptor has a single-layer type and a laminated type, and the electrophotographic photoreceptor of the present invention can be applied to any of them. However, in particular, it can be used for both positive and negative chargeability, has a simple structure and is easy to manufacture, can suppress film defects when forming a photosensitive layer, has fewer interfaces between layers, and can improve optical properties. in the single-layer type. Hereinafter, the electrophotographic photoreceptor of a single-layer type and the electrophotographic photoreceptor of a laminated type will be specifically described.

Abstract

The invention provides an electronic photographic photoreceptor with high sensitivity and an image forming apparatus. An light sensitive layer containing at lest an electron transport agent, an electronic charge generating agent and cementing resin is fixed on the conductive substate of the electronic photographic photoreceptor, wherein the electron transport agent comprises compounds representated by the general formula (1). In the general formula (1), R represents alkyl with with 1-6 carbon atoms having or not having substituent, alkoxyl with 1-6 carbon atoms having or not having substituent, aralkyl with 6-20 carbon atoms having or not having substituent, aryl with 6-20 carbon atoms having or not having substituent, heterocyclic radical with 1-20 carbon atoms having or not having substituent, and cycloalkyl with 3-10 carbon atoms having or not having substituent.

Description

technical field [0001] The present invention relates to a high-sensitivity electrophotographic photoreceptor and an image forming device. Background technique [0002] In the image forming apparatus described above, various photoreceptors having sensitivity in the wavelength region of a light source used in the apparatus are used. One of them is an inorganic photoreceptor in which an inorganic material such as selenium is used for a photosensitive layer, and the other is an organic photoreceptor in which an organic material is used for a photosensitive layer. Compared with inorganic photoreceptors, organic photoreceptors are easier to manufacture, and there are various material options such as charge generators, electron transport agents, hole transport agents, and binder resins, and a high degree of freedom in functional design. Therefore, in recent years, to be commonly used. [0003] Organic photoreceptors include a so-called laminate type photoreceptor formed of a lami...
