ABSTRACT:
An image recording apparatus employs a transfer type recording medium which includes a photosensitive pressure-sensitive recording sheet and a developer sheet. The former sheet is exposed to light to form a latent image corresponding to an image of an original. This sheet is exposed to light while being transported at a speed equal to or in the case of making a copy of enlarged or reduced size, at a speed different from a speed at which the original is scanned by light. The photosensitive pressure-sensitive recording sheet on which the latent image is formed is brought into facial contact with the developer sheet and the latent image is developed under pressure to provide a visible image on the developer sheet. This developing operation is performed while moving the superposed two sheets at the same speed as the speed when the latent image is formed on the photosensitive pressure-sensitive recording sheet. Since both the exposure and developing operations can be performed substantially simultaneously, the copying speed is increased. Further, no receiving unit needs to be provided in a position between the exposure unit and the developing unit, which may otherwise be needed for receiving the exposed recording sheet if development is performed upon completion of the exposure. Thus, the overall apparatus can be made compact in size.
