Abstract
In an image recording apparatus in which an image optically formed on a photosensitive material is transferred as a visible image onto an image receiving material by pressurization, a back-up roller is employed to press a free nip roller against a fixed nip roller so that the pressure at the nip region of the two nip rollers is made uniform over the entire length thereof. The back-up roller has a width smaller than the width of the free nip roller against which it presses, and the back-up roller presses only against a central portion of the free nip roller.
