An image forming apparatus has a latent image carrier for carrying an electrostatic latent image formed thereon. The electrostatic latent image is developed into a visible image which is transferred from the latent image carrier onto a transfer sheet in an image transfer region. The transfer sheet is held on a drum-shaped or a belt-shaped holder with the leading end clamped by a clamp. For efficient image formation, the holder is accelerated and decelerated while the transfer sheet is out of the image transfer region. When the transfer sheet with the transferred image thereon is sent to an image fixing device, the holder is accelerated and decelerated during an interval after the trailing end of the transfer sheet has left the image transfer region and before the leading end of the transfer sheet reaches the image fixing device. After the holder has been accelerated and decelerated, it is positionally adjusted when required.

In an image recording device, particularly suitable for the reproduction of colored images, two images are superimposed on a recording sheet. The second image is so designed that it compensates the undesirable saturation of density under an ordinary condition and that the superimposed image has an improved tone reproduction. The superimposed toner images are heat-fixed together on the print.
