no. 1 approach

[0019] The electrophotographic photoreceptor according to the first embodiment of the present invention relates to a photosensitive layer formed on a conductive substrate, the photosensitive layer contains a charge transport material, and the charge transport material contains an iminoquinone derivative represented by the following general formula (1). Electrophotographic photoreceptors as electron transport materials.

[0020]

[0021] (In general formula (1), R 1 and R 2 are selected from a hydrogen atom, a halogen atom, a nitro group, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 12 carbon atoms which may be substituted by an alkyl group having 1 to 12 carbon atoms, and a carbon A group consisting of an aralkyl group with 6 to 12 atoms, a cycloalkyl group with 3 to 10 carbon atoms, and an alkoxy group with 1 to 6 carbon atoms, R 3 and R 4 are selected from a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 12...

no. 2 approach

[0096] A second embodiment of the present invention relates to an image forming apparatus including: an image carrier; a charging unit for charging the surface of the image carrier; and an exposure unit for exposing the charged surface of the image carrier, thereby an electrostatic latent image is formed on the surface of the image carrier; a developing section for developing the electrostatic latent image into a toner image; and a transfer section for transferring the toner image from the image carrier to a transferred body , the electrophotographic photoreceptor according to the first embodiment of the present invention is used as an image carrier.

[0097] In the image forming apparatus according to the second embodiment of the present invention, structural units other than the image carrier, such as the charging unit, the exposure unit, the developing unit, and the transfer unit, can be obtained from those used in conventional image forming apparatuses. Appropriate choice ...

Description

technical field [0001] The present invention relates to an electrophotographic photoreceptor and an image forming apparatus including the electrophotographic photoreceptor. Background technique [0002] As an electrophotographic photoreceptor included in an electrophotographic image forming device, there are inorganic photoreceptors having a photosensitive layer composed of inorganic materials such as selenium and amorphous silicon; An organic photoreceptor with a photosensitive layer composed of an organic material such as a transport material. 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 wide range of materials, and have a high degree of freedom in design. [0003] As charge transport materials for such organic photoreceptors, electron transport materials and hole transport materials are used, and the use of vario...
