Abstract
A fixing device includes a fixing roller that heats a toner image. A pressure roller forms a nip with the fixing roller by contacting and pressing the fixing roller. Separation claws are disposed side by side along a shaft center of the fixing roller within a sheet passing region of the fixing roller on a downstream side from the nip in a carrying direction of the recording sheet to separate the recording sheet from the fixing roller. Each claw includes a tip that contacts a circumferential surface of the fixing roller. The claws are disposed so that an interval from the nip to the tip of a claw at a position close to at least one end of the sheet passing region becomes smaller than an interval from the nip to the tip of a claw at a position other than the position close to the end.
