Air duct for an electrophotographic image forming device

Abstract

An imaging system according to one example embodiment includes a rotatable photoconductive drum having an outer surface. A rotatable developer roll has an outer surface in contact with the outer surface of the photoconductive drum for supplying toner to the outer surface of the photoconductive drum. A rotatable charge roll has an outer surface in contact with the outer surface of the photoconductive drum for electrically charging the outer surface of the photoconductive drum. An air duct has at least one outlet positioned to direct forced air flowing through the air duct to at least one of the outer surface of the charge roll and the outer surface of the photoconductive drum for indirectly cooling the developer roll without directing forced air from the air duct directly onto the outer surface of the developer roll.
