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.

Description

TECHNICAL FIELD

[0001] The present invention relates to photosensitive material conveying systems that feed out using a feeding out roller a plurality of photosensitive sheet films that have been stacked, and to image forming apparatuses.BACKGROUND OF THE INVENTION

[0002] Thermal development apparatuses are known that execute a thermal development process of forming latent images on a sheet film made of a thermal development photosensitive material and making the images visible by developing using an application of heat, and sheet films stored in a storage container inside a thermal development apparatus are picked up for conveying and supplying the sheet films to the downstream side. In order to pick up such sheet films, although conventionally the suction cup method is used for lifting up the sheet films while adhering to them by vacuum suction, in this suction cup method, the time taken for picking up becomes long, and hence cannot be selected from the point of view of speedy process...
