ABSTRACT:
In an apparatus that employs a photo-sensitive sheet with a surface comprised of photo-sensitive microcapsules containing pigments or precursors thereof and which are selectively hardened when irradiated with a light image of a picture to be developed on a sheet of developing paper by the pressing together of the developing paper and the photo-sensitive sheets; the developing paper and photo-sensitive sheets in contact with each other are transported in a predetermined direction of sheet travel across a back-up surface, and a rotatable roller disposed in opposing relation to the back-up surface and having its axis of rotation extending parallel to the direction of sheet travel is transported relative to the back-up surface in a direction parallel to the latter which is perpendicular to the direction of sheet travel while the roller is urged toward the back-up surface with the contacting developing paper and photo-sensitive sheets therebetween so as to be pressed together at a relatively narrow striped-like area defined by the rolling path of the peripheral surface of the roller.
