Abstract
A fixing device includes a fixing member, a nip formation member, a pressing member, and a low-friction sheet. The nip formation member is provided inside a loop formed by the fixing member rotating in a predetermined direction of rotation. The pressing member is pressed against the nip formation member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The fixing member and the pressing member rotate and convey the recording medium bearing the toner image through the nip. The low-friction sheet, over which the fixing member slides, covers the nip formation member. The nip formation member includes a first sandwiching member covered by the low-friction sheet, and a second sandwiching member sandwiching the low-friction sheet together with the first sandwiching member.
