ABSTRACT:
In an image forming apparatus, the size of sheets (ordinary sheets) set on any tray not set as a tab tray by tab tray setting member is determined by ordinary sheet size sensing member on the basis of the dimension in the sheet feed direction and the dimension in the direction (widthwise) perpendicular to the above direction. On the other hand, the size of sheets (sheets with tabs) set on a tray set as a tab tray is determined by tab sheet size sensing member on the basis only of the dimension in the widthwise direction. If the size of the sheets of the tab tray cannot be determined on the basis only of the above dimension, the size set beforehand is selected. With this configuration, the apparatus is capable of detecting the sizes of various kinds of tab sheets with accuracy.
