An image forming apparatus includes photoreceptor, which comprises substrate and interface layer, electric charge generation layer, electric charge transport layer on substrate in order; the charger charging for photoreceptor; irradiation machine forming electrostatic latent image on the radio photoconductor; image developing apparatus making electrostatic latent image develop on photoreceptor bytoner so as to form toner image; transfer apparatus transferring the toner image on the recording medium; fixing apparatus fixing the toner image on the recording medium; and discharge apparatus removing the residual electric potential on photoreceptor by light, in which, the interface layer comprises metal oxide, electric charge generation layer incorporates organic charge generation material, and irradiation device writes into the ray radiation photoreceptor without absorption in the metal oxide in interface layer by the wavelength shorter than 450nm.
Description
Imaging equipment and imaging method technical field The present invention relates to an image forming apparatus and image forming method using a latent electrostatic image carrier (hereinafter referred to as "electrophotographic photoreceptor", "photoreceptor" or "photoconductive insulator") having a The photosensitive layer of the layer, wherein the charge generation layer includes a charge generation organic material. Background technique Recently, the development of an information processing system utilizing electrophotography is noteworthy. In particular, optical printers in which information converted into digital signals is recorded using light have seen remarkable improvements in print quality and reliability. This digital recording technology is applicable not only to printers but also to copiers, and so-called digital copiers have been developed and used. Copiers using conventional analog recording technology and this digital recording technology have various i...
