Abstract: In accordance with an embodiment, an ink supply device comprises an ink storage section, a float and a floating position detection device. The ink storage section is connected with an inkjet head, and stores ink to be supplied to the inkjet head. The float is arranged in the ink storage section in a floatable manner in response to a height of a liquid surface of the ink. The floating position detection device comprises a detection target arranged on the float, and a target detection section which is arranged in the ink storage section and detects that the detection target approaches. The target detection section is arranged on a wall substantially orthogonal to an axial direction of a rotating shaft of the ink storage section. An inkjet recording device of the embodiment comprises an inkjet head configured to jet ink to an image receiving medium, and the ink supply device.
