Fixing unit with a pressure releasing member and image forming apparatus having the same
A fixing unit which may be disposed in an image forming apparatus includes a heating roller, at least one pressure roller being in pressure contact with the heating roller to form a nip together with the heating roller, and a pressure releasing member partially restricting application of pressure to the nip. The nip includes an effective fixing section used for fixing. The pressure releasing member includes a pair of pressure releasing parts inserted into sections of the nip other than the effective fixing section, a connection part connecting the pair of pressure releasing parts, and guide parts extending from the connection part in the same direction as the pair of pressure releasing parts. The pressure releasing member prevents deformation of a portion of an elastic layer formed on the heating roller which corresponds to the effective fixing section.
