Abstract
Abstract A liquid storing container employable for an ink jet recording apparatus includes a housing, a porous ink absorbing member received in the housing, and a first filter coming in contact with the ink absorbing member. The liquid storing container is detachably connected to an ink jet recording head having a second filter disposed in a liquid flow path thereof. The liquid storing container is constructed such that the volume between the first filter and the second filter, a size of each filter, a condition for compressively receiving the ink absorbing member in the housing, and an inner structure of the liquid storing container satisfactorily coincide with predetermined conditions.
