An image forming device includes a frame, a photosensitive drum, a developing roller, a transfer roller, a heating roller, a backup roller, a peeling claw, and a protection member. The photosensitive drum has a surface on which a latent image is formable. The developing roller develops the latent image to provide a toner image. The transfer roller transfers the toner image onto a recording medium. The heating roller has a heating surface and a shaft supported to the frame and extending in a direction. The backup roller has a shaft supported to the frame and extending in the direction. The backup roller is in pressure contact with the heating roller. The peeling claw has a tip end in sliding contact with the heating surface of the heating roller. The protection member is configured to protect the peeling claw and prevent a user from accessing to the peeling claw.
