A lubricant coating device related to the present invention is characterized in that it comprises a lubricant supply unit 12 which supplies a lubricant 11 onto an outer peripheral surface of an image carrier 1 that is driven to rotate and a lubricant smoothing unit 13 which is disposed on the downstream side in a rotating direction of the image carrier 1 of the lubricant supply unit 12 and smoothes the lubricant 11 supplied onto the outer peripheral surface. In the lubricant coating device, the lubricant smoothing unit 13 rotates while being in surface contact with the outer peripheral surface of the image carrier 1 and thereby smoothes the lubricant 11 supplied onto the image carrier 1 by the lubricant supply unit 12.
