Thermally developing apparatus

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;
• and
• a controller to control heat generation of the plural heaters, the controller controls the plural heaters in such a manner that a control target for a heater at the time that the supplying means supplies the thermally developable material to the heating member is made different from that for a heater at the other time 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° C.
