ABSTRACT:
The present invention provides an image forming device comprising a first roller mechanism for sending out printing paper from a paper feed tray accommodating the printing paper therein, a second roller mechanism for transporting the printing paper to a printing start position where formation of an image on the paper is started, and a power supply mechanism for giving power to the first roller mechanism and the second roller mechanism. The device transports the printing paper at a first transport speed from an accommodated position inside the feed tray to a first position where the paper is transportable by the second roller mechanism, by driving the first roller mechanism, discontinues the driving of the first roller mechanism by the power supply mechanism upon the printing paper reaching the first position, transports the printing paper from the first position to a second position where the paper is taken out of the feed tray at a second transport speed lower than the first transport speed by driving the second roller mechanism, and transports the printing paper from the second position to the printing start position at a third transport speed higher than the second transport speed by driving the second roller mechanism.
