Abstract
A copier has an ejection mechanism for allowing a sheet with a formed image to be ejected via an ejection exit toward the outside of the machine. The ejection mechanism has a switch-back section for allowing the sheet which is passed through a fixing unit at a predetermined process speed to be received for the sheet to be inverted and an ejection roller pair for allowing the sheet which is sent from the switch-back section to be decelerated before the ejection exit and to be sent to the outside of the machine. In order to maintain a conveying pitch at which sheets are continuously delivered, the conveying speed of the sheet passed through the switch-back section is increased, thus shortening the inversion operation time required for the switch-back operation. That is, the conveying speed of the sheet passed through the switch-back section is made higher than the process speed. The thus increased sheet conveying speed is decelerated in a passage of the sheet through the ejection roller pair, so that the ejection of the sheet is prevented.
