摘要： An image-forming apparatus allows duplex print to be performed using tabbed sheets. A plurality of paper sensors A, B, C, D, E, and F are installed on a paper output side of a paper tray 20 in a direction perpendicular to a sheet transport direction. The location of a tab 12 and the tab length in the transport direction are determined from a difference in timings of the rise or fall of output signals from the paper sensors A-F. When the tab 12 is located on the leading edge of the sheet in the transport direction and does not traverse a transport control sensor X, operation timing of a device &agr; which is activated based on the timing of the rising of output signal from the transport control sensor X is advanced by an amount corresponding to the length of the tab 12. On the other hand, when the tab 12 traverses the transport control sensor X, or when a sheet without a tab is used, the operation timing is not advanced. Accordingly, it becomes possible to determine an appropriate operation timing even when a sheet is inverted or reversed for duplex printing.
