ABSTRACT:
An image recording apparatus is disclosed, which includes an exposure portion, a first conveying roller pair, a second conveying roller pair, a V-shaped pressuring piece disposed between the first and second conveying roller pairs, the pressuring piece extending along the lateral direction of the first image recording material and being in contact with a non-exposure surface of the first image recording material, an image-forming-solvent applying portion for applying an image forming solvent onto the first image recording material, and a heating drum for superimposing the first image recording material and a second image recording material together so as to heat develop and transfer an image of the first image recording material to the second image recording material. Thus, since the first image recording material is raised by the pressuring piece, even if the first image recording material is a thin photosensitive material, it can be stably exposed and conveyed. In addition, the first and second driving roller pairs have different diameters so as to keep the first image recording material in tension.
