Abstract
An improved apparatus and method for controlling media temperature to prevent image offset and degloss in an electrostatic image forming apparatus are provided. The apparatus and method utilize a plurality of media support surfaces in the pre-nip media path to reduce heat transfer to the media in this region. An insulating channel is provided beneath the media supports to thermally isolate the media supports. One or more insulating plates may also be provided between the rollers of the fusing nip and the media support surfaces to further reduce heat transfer from the fusing members to the media support surfaces and media.
