Abstract
An image forming apparatus is capable of maintaining a low charged potential on the surface of the guide member, thereby electrostatically preventing generation of paper dust. The image forming apparatus comprises a guide member for guiding the recording material and a rotary member for forming an image on the recording material guided by the guide member, wherein the guide member is composed of a conductive member having a layer of fluorinated resin on a guide surface for guiding the recording material. The fluorinated resin on the guide member is formed by coating and curing fluorinated resin on the conductive member. The guide member serves to change the transported direction of the recording material from the vertical direction to the horizontal direction. Such configuration prevents elevation of the potential on the fluorinated resin, covering the guide member, by friction with the recording material, thereby avoiding generation of paper dust and enabling image formation of high image quality.
