Abstract
A thermic developing station for recording material which is to be developed by means of heat, comprising a rotatable drum and a heating element which is adapted to fit the curvature of the drum surface, the recording material being fed through between the drum and the heating element by the drum and at the entrance of the recording material into the heating zone an unheated member is provided which is also adapted to fit the surface of the drum.
Claims11
A thermal development station for recording material to be developed by means of heat, comprising:
- a rotatable drum;
- an electrical heating element with an associated directly heated base member having a curved surface corresponding to a curvature of a surface of the drum and being positioned such that a recording material can be transported through by the drum in a gap between the drum and the heating element base member as the drum rotates;
- and a thermally isolated member which is substantially less heated than portions of the heating element base member likewise having a curved surface corresponding to the curvature of the drum surface and provided at an entry point for the recording material into a heated zone between the drum and the heating element base member.
