Photosensitive Material Conveying System and Image Forming Apparatus

Abstract

The photosensitive material conveying system is configured so that a feed out roller is contacted on a stack of sheets having a plurality of stacked photosensitive sheet films each of which is provided with an emulsion layer and a first protective layer provided on one side of a supporting base and a second protective layer provided on the other side with matting agent dispersed in the second protective layer, and the topmost sheet film in the stack of sheets is fed out by the rotation of the feeding out roller, wherein the matting agent has a spherical shape, a hardness softer than the first protective layer, and particle diameter in the range of 8 to 12 μm, and the contact pressure of the feeding out roller is 0.49 N/cm or less.

1 . A photosensitive material conveying system which is configured so that a feed out roller is contacted on a stack of sheets having a plurality of stacked photosensitive sheet films each of which is provided with an emulsion layer and a first protective layer provided on one side of a supporting base and a second protective layer provided on the other side with matting agent dispersed in the second protective layer, and the topmost sheet film in the stack of sheets is fed out by the rotation of the feeding out roller, wherein the matting agent has a spherical shape, a hardness softer than the first protective layer, and particle diameter in the range of 8 to 12 μm, and the contact pressure of the feeding out roller is 0.49N/cm or less. 
   
   
       2 . The photosensitive material conveying system according to  claim 1 , wherein the feeding out roller contacts the sheet film on the second protective layer. 
   
   
       3 . The photosensitive material conveying system according to  claim 1 , wherein the feeding out roller has a prescribed width along a direction at right angle to the direction of conveying, and has a pressure adjusting function in order to make the contact pressure uniform over the entire width of the sheet film. 
   
   
       4 . The photosensitive material conveying system according to  claim 1 , wherein the photosensitive sheet film is a thermal development type photosensitive film and the matting agent comprises PMMA (polymethyl methacrylate). 
   
   
       5 . An image forming apparatus comprising the photosensitive material conveying system according to  claim 1 , the image forming apparatus forming an image onto the sheet film having been fed out.
