Abstract (en)

A lubricant supply device (15) supplies a lubricant to a surface of an image bearer (11) at a position downstream from a cleaning blade (14a) in a rotation direction of the image bearer (11). The lubricant supply device (15) includes a conveying path (15g, 15h) configured to feed the lubricant from an inside of the lubricant supply device (15) to an inside of a cleaning device (14) in which the cleaning blade (14a) configured to contact the image bearer (11) is disposed, without passing through the image bearer configured to bear a toner image. The conveying path (15g, 15h) is configured to feed the lubricant to the surface of the image bearer (11) at a position upstream from the cleaning blade (14a) in the rotation direction of the image bearer (11).
