Zusammenfassung:	An ink supply apparatus includes a sub tank connected to a printer head and having an ink reservoir chamber to store a liquid ink. A fluid level detector is configured to detect a fluid level of the liquid ink stored in the ink reservoir chamber. The fluid level detector has a light emitting device, a light receiving device, and a casing having a section through which a light is to pass and which has an outer surface that is to contact the liquid ink. The light emitting device is capable of emitting the light toward the outer surface through the section. The light receiving device is to receive reflected light reflected at the outer surface. A storage amount determining device is configured to determine whether a predetermined amount of the liquid ink is stored in the ink reservoir chamber based on detection results of the fluid level detector.
