One path of the chemical liquid from the chemical liquid supplying member to the chemical liquid collecting member via one of the at least two ink jet heads may be substantially the same as a length of another path of the chemical liquid from the chemical liquid supplying member to the chemical liquid collecting member via the other of the at least two ink jet heads.
