Two roller members support an endless conveying member tensioned around them, where the endless conveying member conveys a printing medium. A first displacing unit displaces a first portion of the endless conveying member in the direction different from the traveling direction of the endless conveying member and a second displacing unit displaces a second portion of the endless conveying member opposite to the first portion in accordance with the displacement of the endless conveying member made by the first displacing unit. The first displacing unit is arranged to displace the portion of the endless conveying member which faces the printing head.
