1. A fusing apparatus comprising:
a pressing roller to be axially rotated;
a fusing belt to rotate by receiving a rotational force from the pressing roller;
a heating element to heat the fusing belt;
a pressing member to press toward the pressing roller from the inside of the fusing belt to form a nip in which printing paper is nipped between the fusing belt and the pressing roller
a sliding layer, on the fusing belt or the pressing member, to reduce friction between the fusing belt and the pressing member, wherein the sliding layer is formed on an inner surface of the fusing belt or a surface of the pressing member, wherein the sliding layer comprises abrasion resistant resin particles including polyetheretherketone (PEEK) and perfluoroalkoxy fluorine resin (PFA) or polytetrafluoroethylene (PTFE), and wherein in the sliding layer, the content of PFA or PTFE is 0 to 50 wt %; and
an adhesive layer, on the fusing belt or the pressing member, to adhere the sliding layer to the fusing belt or the pressing member.
