<p>PROBLEM TO BE SOLVED: To suppress temperature rise at the ends of a fixing belt during the fixation of images on sheets without consuming unnecessary energy, prevent side effects, such as reduction in energy-saving property, extension of warm-up time, and drop in temperature, and ensure sheet separability.SOLUTION: A fixing device 20 includes a fixing rotating body 21, an opposing rotating body 22 that is provided opposite to the fixing rotating body, a heat source 23 that heats the fixing rotating body, a nip forming member 24 that is disposed inside the fixing rotating body 21, and a support member 25 that supports the nip forming member 24; and fixes an unfixed image on a recording medium P at a nip part N formed by the fixing rotating body 21 and opposing rotating body 22, where the nip forming member 24 has a substrate 51, and a first thermal conduction member 41 having higher thermal conductivity than that of the substrate on the nip part side of the substrate, and the first thermal conduction member 41 has a projection 45 projecting downward formed on the nip exit side of the first thermal conduction member 41.</p> |
