摘要:
A fuser for an electrophotographic imaging device according to one embodiment includes a stationary pressure member having an elongated body with an outer surface. The pressure member is substantially transparent and/or substantially translucent and permits the passage of radiant heat therethrough. An endless fusing belt having a flexible tubular configuration is rotatably positioned about the pressure member. The pressure member is positioned around a heating lamp for transmitting radiant heat through the pressure member to an inner surface of the fusing belt. A backup roll opposes the fusing belt. The pressure member is configured to apply pressure contact to the fusing belt against the backup roll to form a fuser nip between the backup roll and a segment of the fusing belt.

An image-forming device includes a belt based fuser for fixing an image to a media substrate. The fuser includes a heater having a base component with at least one heating element disposed thereon. The heater further includes a covering layer covering the at least one heating element providing a substantially even surface to abut a belt. Unevenness, which may be present on the substantially even surface, has a height, defined by a base and a peak, of less than about 10 μm. A process for producing the heater is also disclosed. The process includes disposing one or more heating elements on a base component of the heater, covering the heating elements of the fuser heater with a covering layer and providing a substantially even outer surface to abut a fuser belt.
