Abstract
A system capable of suppressing the variation of a conveyance speed of a medium occurring when the rear end of the medium gets away from between a pair of rollers to surely and stably conduct the processing (transfer of a visible image) for the medium in a processing section (a transfer position). Accordingly, this system includes a position detecting section for detecting a position of the medium conveyed, and a control section for, when the position detecting section detects the fact that the rear end of the medium exists at a position immediately before getting away from between resist rollers, executing control so that a medium conveyance speed by the resist rollers becomes equal or substantially equal to a medium conveyance speed by conveyance rollers. This system is applicable to printers including an electrophotographic system.
