Abstract:
A fixing device includes a pressure roller and a pressure pad that form a nip portion, and a nip member disposed opposite to the pressure roller as viewed from the pressure pad. The pressure pad is formed of an elongated flat-plate member and includes a first main surface located on a pressure roller side and a second main surface located on a nip member side. The nip member includes a receiving portion abutting against the pressure pad in a pressed state. A portion of the second main surface which corresponds to a passage region of the recording material provided at the nip portion is provided with a plurality of recesses, and the entire perimeter of each of the plurality of recesses is surrounded by projections. Top surfaces of the projections are in close contact with the receiving portion in the pressed state.

Claim (Index 18):
A fixing device that heats and pressurizes a toner image, which is formed on a recording material, at a nip portion provided in a transport path for the recording material to fix the toner image onto the recording material, the fixing device comprising:\n a heating source for heating a toner image formed on the recording material; a pressure roller and a pressure pad disposed to face each other with the transport path therebetween so as to form the nip portion; and a nip member disposed opposite to the pressure roller as viewed from the pressure pad for nipping the pressure pad between the pressure roller and the nip member in a pressed state in which the pressure pad is pressed by the pressure roller, wherein the pressure pad is formed of an elongated flat-plate member extending in a width direction parallel to an axial direction of the pressure roller and includes a first main surface located on a pressure roller side and a second main surface located on a nip member side, the nip member includes a receiving portion abutting against the pressure pad in the pressed state, a portion of the second main surface which corresponds to a passage region for the recording material provided at the nip portion is provided with a plurality of projections each having an elongated projection shape and being sandwiched between recesses in a direction orthogonal to a pressing direction of the pressure roller, and each of top surfaces of the plurality of projections is in close contact with the receiving portion in the pressed state.
