PURPOSE:To straighten the curl generated in a heat developing and transferring stage by providing a straightening guide path having the bend in the direction opposite from the direction of the curl appearing in the heat developing or transferring stage behind an outlet of said stage and passing a heat developable photosensitive material at >=50 deg.C in the inlet part of the straightening guide path. CONSTITUTION:While the material is passed between a heating drum 1 and a conveyor belt 2 facing said drum, the material is subjected to the heat development and transfer by the heat from the heating drum 1. The straightening guide path X which consists of a pair of curved plates 3A, 3B facing each other and has a small curvature in the inlet part and larger curvature in the outlet part is provided on the outlet side of such heat developing and transferring device. The material passes the guide path X in the state of having sufficient excess heat. The temp. in at least the inlet part of the straightening guide path is desired to be >=80 deg.C. The curl occurring in the heat developing and transferring stage is thereby straightened.
