Abstract:
     A thermal development apparatus includes a heating drum and rollers. The heating drum with a smooth layer having an arc shaped portion of an outer circumferential surface heats and carries photothermographic imaging material being in contact with the arc-shaped portion, and opposed rollers arranged in line along a carrying path of the material presses the material to the outer circumferential surface of the arc-shaped portion. When R (mm) denotes radius of arc-shaped portion, r (mm) denotes radius of opposed rollers, alpha (degree) denotes angle between lines respectively connecting center of arc-shaped portion and centers of two opposed rollers adjacent to each other, P (mm) denotes pitch of opposed rollers, and beta (degree) denotes contact angle of material to opposed roller, P=2piRalpha/360, 2r 3>=P>2r, and beta<=60 are satisfied.
