IMAGE HEATING DEVICE AND IMAGE FORMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/054814
Kind Code:
A1
Abstract:
In this image heating device, a control unit controls power supplying to a plurality of heat generation bodies so that a first average temperature and a second average temperate are in a prescribed temperature range, the first average temperature being an average value of a control target temperature of a heating region included in a first region of one end side rather than a central heating region in a direction that is orthogonal to a carrying direction of a recording material among a plurality of heating regions heated by a plurality of heat generation bodies of a heater, and the second average temperature being an average value of a control target temperature of a heating region included in a second region of the other end side rather than the central heating region.
