<p>A sheet resist apparatus (1) disposed in a transporting path of a recording sheet (18) transported from a sheet supplying unit (17) to an image forming unit (10) which forms an image on the transported recording sheet in an image forming apparatus, includes: a pair of first rollers (22) disposed in the transporting path; a pair of second rollers (23) disposed in the transporting path at a downstream of the first rollers; a first driving device (43) for rotating the first rollers to transport the recording sheet toward the second rollers; and a second driving device (35) for rotating the second rollers to transport the recording sheet, which is transported from the first rollers, toward the image forming unit in synchronization with a timing of image-formation of the image forming unit. The sheet resist apparatus further includes: a sensor (24) disposed between the first rollers and the second rollers for detecting a tip of the recording sheet transported from the first rollers; and a control device (47) for controlling the first and second driving devices on a basis of a result of detection of the sensor, such that the first driving device stops driving once before the tip reaches the second rollers, and such that the first driving device resumes driving earlier than the second driving device starts driving by a predetermined time period. <IMAGE></p> |
