Abstract

PURPOSE:To uniformly and closely superpose a photosensitive material and an image receiving material without involving air by providing an electrostatic charging means for causing the photosensitive material and the image receiving material to generate electric fields with which both materials are attracted to each other at the time of superposing them. CONSTITUTION:The photosensitive material 16 and the image receiving material 48 supplied to a superposing roller 52 are superposed by the roller 52 and guided to be supplied between a heating drum 40 and an endless press-contacting belt 42 in a state where they are still superposed. In such a case, the image receiving material 48 supplied to the superposing roller 52 is directly electrostatically charged by an electrostatic charger 70. Therefore, the photosensitive material 16 and the image receiving material 48 generate the electric fields with which they are attracted to each other at the time of being superposed. Thus, both materials are attracted to each other without involving the air when they are superposed by the superposing roller 52, thereby uniformly and closely superposing them.

When the photosensitive material 16 and the image-receiving material 48 are sandwiched and conveyed and reach the lower part of the heating drum 40 , the peeling claw 56 engages with the tip of the photosensitive material 16 and separates the photosensitive material 16 from the image-receiving material 48 . While peeling from the outer periphery, the peeling roller 5
8 presses the photosensitive material 16 onto the heating drum 40, wraps the photosensitive material 16 in a peeled state with the peeling claw 56, and bends and guides it downward.

In this embodiment, the image receiving material 48 supplied to the overlapping roller 52 is directly charged by the charger 70, thereby creating an electric field between the photosensitive material 16 and the image receiving material 48 that attract each other to each other. However, the present invention is not limited thereto, and as shown in FIG.
2, the photosensitive material 16 and the image receiving material 48 are
It is also possible to adopt a configuration in which a charge is applied to the . In this case as well, an electric field that attracts each other is generated between the two materials, and the photosensitive material 16 and the image-receiving material 48 are attracted to each other and are superimposed in close contact with each other.
