Image forming device and image forming method providing notifications for pressure contact force adjustments

An image forming device comprising:

• a toner image former that forms, on a paper sheet, a toner image based on image information;
• a fixer that includes at least a pair of rollers, the pair of rollers including a heating roller and a pressurizing roller, and that fixes the toner image by nipping, at a pressure contact portion formed by the pair of rollers, the paper sheet on which the toner image is formed;
• an adjuster that adjusts a pressure contact force at the pressure contact portion to either a first pressure contact force or a second pressure contact force that is weaker than the first pressure contact force;
• and
• one or more controllers that control execution of a first job related to image formation via the fixer, wherein
• after a paper jam that has occurred in a vicinity of the fixer is cleared, the one or more controllers provide a user with a notification that prompts the user to operate the adjuster for adjusting the pressure contact force to either the first pressure contact force or the second pressure contact force, such that the pressure contact force becomes appropriate based on a paper type of the paper sheet.
