    摘要： Provided is an elastic member for ink jet, including a styrene-based thermoplastic elastomer and a thermoplastic resin, in which the elastic member further includes at least a nonionic surfactant having an ethylene oxide adduct, and the content of the nonionic surfactant is 0.1 to 5 mass % with respect to the styrene-based thermoplastic elastomer. The elastic member has sufficient releasability and high liquid-contact properties, which suppresses clogging of ejection orifices due to precipitation when eluted in ink.

    摘要： The present invention provides an ink jet cartridge configured such that an absorber is housed in one space while ink is accommodated in the other space, the ink jet cartridge keeping the ink sealed during distribution. The ink jet cartridge has an ink tank portion that accommodates ink, a print head portion that ejects the accommodated ink, and an ink supply path connected between the ink tank portion and the print head portion. A seal member that seals the ink supply path is located on an ink tank portion side of the ink supply path.

    摘要： An ink tank is provided which can apply an optimum negative pressure stably by a valve of a simple structure. To this end, the ink tank of this invention has a valve and a damper section installed in an ink flow path. The valve deforms when the negative pressure in the ink supply port is greater than a predetermined level, to temporarily open the ink flow path to introduce ink from the ink accommodation portion to the ink supply port. The damper section is installed between and communicates to the ink supply port and the valve in the ink flow path. The damper section is formed of a resilient member more easily deformed than the valve and applies a negative pressure to the interior of the ink supply port by an elastic recovery force of the resilient member.
