A sheet feeding system for ensuring feed of a single sheet includes a suction cup for holding the uppermost sheet of a stack. During initial lifting of the sheet, movement of the suction cup is halted for a predetermined time to allow sheets which have clung, by static attraction or otherwise to the uppermost sheet, to return to the stack. The initial lifting of the sheet takes place by swinging the suction cup about an axis. Thereafter the suction cup is lifted vertically to bring the topmost sheet into position to be taken up by portion feeding rollers and fed into a feed path. A stack empty detector employs a swinging arm which is positioned above the position the position of initial displacement of the suction cup so that, even if the last few sheets of the stack are initially attracted by the suction cup, the indicator will be prevented from giving a spurious 'stack empty' signal.

In an imaging device for forming a visible image on a recording medium by pressurizing the recording medium, provided are means for detecting a certain position of the recording medium to be pressurized before the recording medium is pressurized, and means for controlling timing of beginning and stopping to pressurize the recording medium based upon a result of the detecting operation. Thus, the recording medium is accurately begun to pressurize at the leading end and stopped to pressurize at the trailing end regardless of a variation of a travelling speed for the recording medium.
