摘要： A fixing device includes a fixing rotator, a hollow pressure rotator, a heater, a holder, and a bearing. The pressure rotator is configured to contact the fixing rotator. The heater is disposed inside the pressure rotator. The holder is configured to hold the pressure rotator and the heater. The bearing is configured to rotatably support the pressure rotator. The holder includes a curved face contact portion having a curved face conforming to an outer circumferential surface of the bearing to contact the bearing. The bearing includes a flange. The flange is configured to divide the bearing into an inboard area and an outboard area in an axial direction of the pressure rotator. The inboard area and the outboard area are asymmetrical.

摘要： A detector (11) of the present invention detects cessation of input to an input form by a user. A generator (12), when input is started again by the user after the user ceased input, acquires an input status of input to the form by the user that was outputted from a monitor that monitors the input status of the input of the information by the user, estimates a cause for input being ceased by the user based on the input status, and then, based on the estimated cause, generates a new input form for which input conditions have been relaxed.
