ABSTRACT:
An image forming apparatus includes a plurality of image carriers on each of which a toner image is formed based on image data; an intermediate transfer belt that is in contact with the image carriers, endlessly stretched over a plurality of rollers; a primary transfer unit that transfers the toner images to the intermediate transfer belt; a secondary transfer unit that transfers the toner images on the intermediate transfer belt to a recording medium at once; a cleaning blade that removes a residual toner on the intermediate transfer belt after a secondary transfer; and a lubricant supplying unit that supplies a lubricant to at least one of the image carriers and the secondary transfer roller, so that the lubricant is supplied to the intermediate transfer belt indirectly.
