Abstract:
A thermally developing apparatus, comprising:a heating member to heat a thermally developable material;supplying means for supplying the thermally developable material in a predetermined supplying direction to the heating member;the heating member comprising plural regions aligned in a direction substantially perpendicular to the supplying direction of the thermally developable material by the supplying means;plural heaters each provided separately to one of the plural regions and to heat a corresponding one of the plural regions of the heating member; anda controller to control heat generation of the plural heaters, the controller controlling at least one of the plural heaters in accordance with a size of the thermally developable material which is a dimension substantially perpendicular to the supplying direction, so that a temperature variation on the heating member in the direction substantially perpendicular to the supply direction is kept within a range of 2.0.degree.
