摘要： An image forming apparatus (11) includes a charge removing device (20) for removing the residual charge on a photosensitive film (12). The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film (12). Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.

摘要： A method for manufacturing an electrophotographic organic photoconductor is disclosed which comprises the steps of forming on the surface of a conductive base a charge transport layer consisting of a first resin composition and forming on the surface of the charge transport layer a charge generating layer consisting of a second resin composition. In this method, the step of forming the charge transport layer includes the application of a charge transport layer coating solution containing the first resin composition and a solvent onto the surface of the conductive base for the formation of a layer of the coating solution and the heat treatment of the coating solution layer at a temperature higher than the glass-transition temperature (Tg) of the first resin composition and lower than the melt-starting temperature of the first resin composition.
