Abstract
Abstract An ink jet cartridge has a recording head portion and an ink containing portion which are detachably mountable relative to each other. The recording head portion ejects ink to effect recording with the ink. The cartridge includes a first ink container, provided in the recording head portion, for containing the ink; a second ink container, provided in the ink containing portion, for containing the ink; and an ink communication tube for establishing ink communication between the first ink container and the second ink container, wherein the ink communication tube is not externally exposed. An ink jet recording apparatus includes a recording head for ejecting ink, an ink container detachably mountable to the recording head for containing the ink to be supplied to the recording head, a detecting device for detecting mounting of the ink container to the ink jet recording apparatus and a control device for controlling a recording operation of the ink jet recording apparatus in accordance with an output of the detecting device.
