Abstract: A thermal development image forming apparatus includes an exposure section, an overlapping section, a developing/transfer section, a sheet separating section, and a correcting section. The exposure section forms a latent image by exposing a photosensitive sheet. The overlapping section overlaps the exposed photosensitive sheet on an image-receiving sheet. The developing/transfer section heats/presses the overlapped sheets so as to develop the latent image on the photosensitive sheet and transfer the developed image onto the image-receiving sheet. The sheet separating section separates the photosensitive sheet from the image-receiving sheet image upon image development/transfer. The correcting section for correcting skews of the sheets in a feed direction is arranged in a step prior to that of the sheet separating section.
