Abstract

A pressure developing device has a pair of pressure developing rollers for pressing a photosensitive and pressure-sensitive recording sheet with a latent image formed thereon and a color developer sheet in overlapping relation to develop the latent image into a visible image and transfer the visible image onto the color developer sheet. The pressure developing rollers have respective pressing surfaces for pressing the photosensitive and pressure-sensitive recording sheet and the color developer sheet, and at least one of the rollers has non-pressing surface extending axially of the roller.
