A fixing device includes a heating member, a pressure member forming a nip portion with the heating member; and a separation member disposed on a downstream side of the nip portion in a medium conveyance direction, wherein the separation member includes a guide portion having a guide surface for guiding the recording medium to be conveyed, and a condensation portion formed at a position remote from the guide surface, to promote generation of water droplets due to condensation at the condensation portion and to prevent recording failures from occurring due to condensation by evaporating the generated water droplets at the condensation portion.
