To sequentially supply sheets from a paper supply part 121 for continuously forming images, for each of second and subsequent sheets, the control unit Cont temporarily stops the paper feed operation after the sensor detects the front end of the sheet after the start of the paper feed operation by the paper feed roller, and then re-starts the paper feed operation. The control unit adopts, as a time from the start of paper feed operation to the re-start of paper feed operation, a specified time (a-d) set to the longest time or longer among the times required from the start of paper feed operation to the re-start of paper feed operation at a sheet front end stop position after the front end of the sheet is detected by the sensor which are obtained by taking at least one of the causes of a variation in the conveyance of sheets into account.
