BACKGROUND

In some image forming apparatuses such as printers and multifunctional machines, the entire surface of a photosensitive body is uniformly charged by a charging device at the time of an image forming operation. Light is irradiated to the uniformly charged surface of the photosensitive body by an exposure device to form an electrostatic latent image of print data. Toner is adsorbed to the electrostatic latent image for development thereof by a developing device. A developed toner image on the photosensitive body is primarily transferred to a transfer belt, and the toner image on the transfer belt is secondarily transferred to paper. The secondarily transferred toner image on the paper is fused on the paper by a fixing device, and the paper is discharged to a paper tray or the like.

Some of these image forming apparatuses are provided with a lubricant application device for applying a lubricant to the surface of the photosensitive body. Some of the lubricant application devices have an application roller provided with application bristles about an outer circumferential surface thereof. The application roller is rotated by a motor, and receives a lubricant from a lubricant supply source and applies the lubricant to the photosensitive body. The application bristles of the application roller may be in constant abutment with the photosensitive body.
