Abstract
A transfer fixing device includes a transfer fixing member, a pressure member, and a primary heater. The transfer fixing member defines a moving surface on which a toner image travels. The pressure member is pressed against the transfer fixing member to define a transfer fixing nip where the toner image traveling along the moving surface meets a surface of a recording medium traveling along the media conveyance path. The primary heater is located upstream of the transfer fixing nip along the media conveyance path to heat the surface of the recording medium before entering the transfer fixing nip. The heated surface of the recording medium fuses toner for transfer and fixing into place at the transfer fixing nip. The pressure member is at least partially electrically biased to generate an electrostatic field to promote transfer of toner at the transfer fixing nip.
