ABSTRACT:
A technology capable of suppressing the generation of transfer scattering of a toner image on an intermediate transfer body and contributing to an improvement in image quality in an image forming apparatus employing an intermediate transfer system is provided. An image forming apparatus is configured to include an intermediate transfer body to which a toner imager is transferred from an image carrier, the intermediate transfer body having an elastic surface layer having a center point average roughness of 0.1 times or more of a volume average particle size of a used toner and a ten-point average roughness of not more than the volume average particle size of the used toner; and a development section which develops an electrostatic latent image on the image carrier by using a toner having a shape factor SF-1 in the range of from 100 to 130 and a shape factor SF-2 in the range of from 100 to 140.
