Abstract
Two lowermost heating members and one intermediate heating member are provided for a plurality of paper feeding trays disposed in the paper feeding portion of an image forming apparatus and the temperature in the whole paper feeding portion is controlled by supplying power to each of the heating members. The heating member is provided with a heat reflective plate and a heat insulating plate side by side to insulate the heat of a heating element. The heating member is placed close to the tray and the temperature in the whole paper feeding portion is controlled under a convection current of the heat emanated from the heating element in the paper feed. Moreover, a humidity sensor may be installed on the side or within the image forming apparatus to control the power supplied to each heating member.
