Abstract:
1. A transfer-fixing device for transferring a toner image to a transfer-fixing surface of a recording medium and fixing the toner image on the recording medium, the transfer-fixing device comprising: a transfer-fixing member to carry the toner image; a pressing member to press against the transfer-fixing member at a support roller to form a nip portion to which the recording medium is conveyed; a heating device to heat the transfer-fixing surface of the recording medium conveyed toward the nip portion, the heating device including a plurality of heating bodies spaced apart in a width direction thereof such that the heating device selectively heats an image region on the surface of the transfer-fixing member; a temperature equalizer to equalize a temperature distribution of a surface of the transfer-fixing member in a width direction of the transfer-fixing member after the surface of the transfer-fixing member passes through the nip portion, the temperature equalizer contacts the transfer-fixing member in an area where the transfer-fixing member is not in contact with the pressing member and the support roller forming the nip; and a magnetic force generator to generate magnetic force, wherein the heating device includes a brush-like member to have a magnetic property and contact the transfer-fixing surface of the recording medium to transfer heat thereto, and the magnetic force generated by the magnetic force generator provides the brush-like member to contact against the recording medium.
