Abstract
A liquid supply system includes a liquid supply container provided with a liquid supply portion for supplying liquid to outside; and a detector which detects presence or absence of the liquid in the liquid supply container, using an electrostatic capacity between the liquid in the liquid supply container and the electrode. The electrode is disposed to be parallel with and spaced from a bottom surface of the liquid supply container, and the bottom surface is inclined relative to a horizontal plane from one end to another end of the liquid supply container, and has a connecting portion at a lower side end.
