Ink cartridge and recording apparatus

Abstract

To be capable of preventing the erroneous detection of the residual amount of ink, and to facilitate exchange work. Provided is an ink cartridge including: a flexible ink bag, configured to store ink and change a thickness thereof in response to an amount of the ink; a housing that houses the ink bag; an outflow port that is formed on a front surface of the housing, communicates with the ink bag, and causes the ink to flow out of the inside of the ink bag; a first detection window and a second detection window, which are formed on the housing; a plate that is fixed to an upper surface of the ink bag, and moves together with the ink bag in response to fluctuations of the amount of ink; an “empty” detecting member that is set movable following the plate in the housing, and moves to a position of closing the first detection window when the ink runs out; and a “full” detecting member that is set movable following the plate in the housing, and moves to a position of closing the second window when a fixed amount or more of the ink is stored in the ink bag.
