Abstract
An image forming apparatus comprising a lubricant supplying device which supplies a lubricant to a rotating image carrier, wherein the lubricant comprises at least one of low molecular weight polytetrafluoroethylene, a fluorine-containing resin including a filler, polytetrafluoroethylene which has been subjected to heat or radiation decomposition treatment, a fluorine-containing resin which has been prepared by a compression molding method, and a porous fluorine-containing resin. The lubricant preferably has a concave portion on the surface thereof contacting the image carrier. The lubricant is preferably disposed so that an acute angle formed by a line parallel to a compression direction of the lubricant, during the compression molding of the lubricant, and a line parallel to a moving direction of the image carrier, is from about 45 to about 90.degree..
