Abstract:
An image forming apparatus comprising:an electrophotographic photoreceptor including a photosensitive layer formed on a conductive support; exposure means for exposing the photoreceptor to form an electrostatic latent image; developing means for visualizing the latent image with a toner into a visualized image; and transfer means for transferring the visualized image to a transfer medium, wherein the conductive support in the photoreceptor has a surface roughness defined by the equation: (0.0006x+0.34) &mgr;m<=Rmax<=2.5 &mgr;m â€ƒwhere roughness is represented by the maximum roughness Rmax and x is a resolution, and means for adjusting the lower limit of maximum roughness Rmax based on resolution so that the lower limit of Rmax increases as a function of increasing resolution and decreases as a function of decreasing resolution; and an undercoating layer is formed between the photosensitive layer and the conductive support.
