There is described an image forming apparatus to form an image on a transfer sheet, in which an image bearing member, image exposing unit for forming a latent image, developing unit for developing the latent image, an intermediate image bearing member for bearing a toner image on its surface, first transfer member for transferring the toner image from the image bearing member to the intermediate image bearing member or the first side of the transfer sheet, second transfer member for transferring said toner image from the intermediate image bearing member to the second side of the transfer sheet, fixing unit for fixing the toner images on the both sides of the transfer sheet, detector for detecting a reference position on the intermediate image bearing member, and controller for controlling timing to start forming the latent image and/or timing to feed the transfer sheet to the first transfer member on the basis of the detection of the reference position on the intermediate image bearing member, are. included.

Duplex image-forming apparatus

An image transmission apparatus includes an original reading unit, a memory, a communicating unit, an impressing unit, and a controller. The memory stores an image signal read by the original reading unit. The impressing means impresses a predetermined stamp on an original. The controller controls the impressing unit so that different stamps are impressed when the read image signal is directly transmitted by the communicating unit and when the read image signal is stored in the memory means.
