Claims

[Claims for Utility Model Registration] 1. A cleaning blade whose tip is pressed against the surface of a toner image carrier that is moved with residual toner attached to the surface, and this blade removes residual toner from the surface. A toner image transfer type multifunction machine equipped with a cleaning device for removing and cleaning a toner image carrier, the device includes means for applying a lubricant to the surface of a toner image carrier after being cleaned, and controlling the operation of the lubricant applying means. and a control means for limiting the surface portion of the toner image carrier to which the lubricant is applied to only a portion that will not be used for toner image formation until it is subsequently cleaned. Transfer type copying machine. 2. A utility model characterized in that the lubricant application means comprises a lubricant application roller that is in rolling contact with the surface of the toner image carrier, and a solid lubricant that is pressed against the surface of this roller. A toner image transfer type copying machine according to claim 1. 3. Registration of a utility model characterized in that the solid lubricant can move toward and away from the surface of a lubricant application roller, and the operation of the lubricant application means is controlled by controlling the movement toward and away from the surface of the lubricant application roller by a control means. A toner image transfer type copying machine according to claim 2.
