摘要： In order to avoid damages or deformations to ejection energy generating elements formed on a substrate or grooved plate, when the substrate and the grooved plate are joined, a liquid ejection head for an image forming apparatus includes a substrate having electro-thermal energy conversion elements thereon, a grooved plate having grooves formed at positions corresponding to the electro-thermal energy conversion elements, ejection ports communicating with the respective grooves, and liquid paths communicating with the ejection ports. At least two protrusions are formed on the substrate apart from each other and corresponding engaging recessed portions are formed on the grooved plate for engaging the protrusions. A height from the surface of the substrate to upper ends of the protrusions is set higher than a height from the surface of the substrate to upper ends of the electro-thermal energy conversion elements or other micro processed portions.

摘要： An ink tank for storing ink supplied to an ink jet recording head includes an ink tank body, an ink absorbing member inserted in the ink tank body in a compressed state, an atmosphere communicating port for communicating an inner space of the ink tank body with the atmosphere, and an ink supply port coupled to the ink jet recording head and serving as an ink supply port. A corner of the ink absorbing member which would be located near the atmosphere communicating port is cut out, a portion of the ink absorbing member around the cutout area is partly released in a degree of compression as compared with the other portion thereof under the state where the ink absorbing member is inserted in the ink tank body in a compressed state, and a space area is formed between the cutout area of the ink absorbing member and the atmosphere communicating port. The ink absorbing member is prevented from entering a buffer chamber, the ink impregnated in the ink absorbing member is uniformly supplied to the recording head, and the ink is prevented from leaking to the outside even if the cartridge is subjected to a thermal impact or a pressure reduced state.
