Fixing device and image forming device

An image forming device comprising an imaging forming part for forming an image and transferring the image on a recording sheet and a fixing device for fixing the image onto the recording sheet by applying heat and pressure to the recording sheet and the image thereon while the recording sheet is passing through a fixing nip, the fixing device including:

• a pressure belt movable in a revolving motion;
• a rotatable fixing roller;
• and
• a pressure member for pressing an inner circumferential surface of the pressure belt toward the fixing roller, the fixing nip being formed between the fixing roller and the pressure belt while an elastically deformable surface of the fixing roller in rotation is brought into contact with an outer surface of the pressure belt by a pressure applied by the pressure member to the inner circumferential surface of the pressure belt,
• the pressure member including:
• an elastic pressure member for applying pressures to the fixing roller to cause a pressure distribution in which a greater pressure is applied to a center of the fixing roller than to each of ends thereof, the center and the ends being along an axis direction of the fixing roller;
• and
• a hard pressure member that is disposed parallel to the elastic pressure member on downstream side of the elastic pressure member in a direction of the revolving motion of the pressure belt and applies pressures to the fixing roller to cause a pressure distribution in which a greater pressure is applied to each of the ends of the fixing roller than to the center of the fixing roller.
