ABSTRACT:
An image-receiving member of sheet material has a portion on which a positive image is adapted to be formed. A pod of processing liquid is secured to the sheet material outside of the image-forming portion. Each pod is preferably divided into two processing fluid containing portions, such that an advancing roller can contact the flat portion devoid of processing liquid in order to advance the image-receiving sheet without rupturing the pod. The mask defining the area on which a positive image is formed, can be either a continuous sheet having openings at regular intervals, or it can be formed by connector sheets alternately coupled to image-receiving sheets in combination with longitudinal masking strips affixed directly to the image-receiving sheet.
