ABSTRACT:
A lubricant applying unit includes application mechanism that applies a lubricant from a solid lubricant on a surface of an image carrier that carries an image. The lubricant is a silicon-based-powder or a silicon-based-granule. Since the lubricant is less likely to adhere on a charging member that comes in contact with the image carrier, insufficient charge in the charging roller can be prevented, and a lifetime of the charging roller increases.
