Tank having first liquid chamber whose portion is positioned rearward of second liquid chamber to increase volume of the first liquid chamber

A tank configured to store first liquid and second liquid to be supplied to a liquid consuming device, the tank comprising:

• a first liquid chamber configured to store the first liquid, the first liquid chamber having a first volume;
• a first front wall through which a liquid surface of the first liquid stored in the first liquid chamber is configured to be viewed from an outside of the tank;
• a first upper wall extending rearward from the first front wall to cross the first front wall, the first upper wall having a first injection hole in communication with the first liquid chamber;
• a second liquid chamber configured to store the second liquid, the second liquid chamber having a second volume;
• a second front wall through which a liquid surface of the second liquid stored in the second liquid chamber is configured to be viewed from the outside of the tank;
• and
• a second upper wall extending rearward from the second front wall to cross the second front wall, the second upper wall having a second injection hole in communication with the second liquid chamber,
• wherein the first liquid chamber defines:
• a first space aligned with the second liquid chamber in a left-right direction, the first space being defined at least by the first front wall and the first upper wall;
• and
• a second space in communication with the first space, the second space being arranged rearward of both the first space and the second liquid chamber, the second space being aligned with both the first space and the second liquid chamber in a front-rear direction,
• wherein the first liquid chamber has a rear end defined by a first rear wall opposing the first front wall in the front-rear direction,
• wherein the second liquid chamber has a rear end defined by a second rear wall opposing the second front wall in the front-rear direction,
• wherein the first rear wall of the first liquid chamber is positioned rearward of the second rear wall of the second liquid chamber in the front-rear direction, and
• wherein the first volume of the first liquid chamber is larger than the second volume of the second liquid chamber.
