Abstract

Abstract An ink-jet cartridge includes an ink-jet head body and an ink storage portion which include coupling members, respectively. The ink storage portion includes an absorbing member, while the ink-jet head body includes an ink communication pipe with an ink-introducing port held in pressure abutment with the absorbing member to compress the absorbing member when the ink-jet head body is coupled to the ink storage portion. This assures a good flow of ink to the ink-jet head body.
