Methods for deposition of elemental metal films on surfaces using metal coordination complexes are provided. The laser beam has a line shape elongated in a perpendicular direction to a scanning direction. Also, a cleaning device has this cleaning member, and a process cartridge and an image forming apparatus have this cleaning device. The X, Y and Z distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down internal core profile. The exhaust region has at least one exhaust aperture, and may include an exhaust slot, a plurality of connected exhaust slots or a plurality of exhaust apertures.
