Abstract

Abstract A storage container for housing and storing an ink jet cartridge which has a recording head to discharge ink, and an ink tank to contain ink to be supplied to the recording head and which is structured to be exchangeable with respect to a recording apparatus comprises a capping member to be in contact with the ink discharge port surface of the recording head to cover the surface thereof and absorbing members conductively connected to the capping member to absorb ink which leaks from said recording head. With the capping member and absorbing member, an airtightness higher than that of the discharge ports is secured to suppress the ink evaporation from the discharge ports of the recording head while the cartridge which is still in use is kept in the storage container. <IMAGE>
