ABSTRACT:
An image forming apparatus forms desired images continuously onto print sheets. The apparatus includes a printing part, a primary sheet feed mechanism for extracting one by one the print sheets stacked on a sheet feed table, and a secondary sheet feed mechanism for taking each print sheet extracted by the primary sheet feed mechanism and for feeding the print sheet toward the printing part at a rate corresponding to the printing speed of the printing part. The secondary sheet feed mechanism further comprises a timing roller and a guide roller in contact with the print sheet for feeding thereof, an electromagnetic clutch for intermittently activating one of the timing roller and the guide roller, and a controller for receiving a detection signal showing a rotating status of the printing part and for supplying the electromagnetic clutch accordingly with an output signal in synchronism with the rotating status.
