A liquid discharge apparatus includes: nozzles discharging liquid; a liquid discharge head including nozzle arrays where the nozzles are arranged in one direction; a liquid adsorbent adsorbing liquid attached to a portion of the liquid discharge head where the nozzle arrays are formed; a moving means for relatively moving the liquid adsorbent in an arrangement direction of the nozzles; support rollers supporting the liquid adsorbent so as to allow the liquid adsorbent to rotate; a rotating shaft corresponding to the axis of rotation of the support roller and being rotated in a normal or reverse direction by using the relative movement of the liquid adsorbent, which is caused by the moving means, as a source of power; and a reverse rotation preventing means for transmitting the normal rotation of the rotating shaft to the support roller and not transmitting the reverse rotation of the rotating shaft to the support roller.
