摘要： An ink jet recording head includes a recording element base plate having an ink heating portion for heating ink, and ink discharge ports for discharging ink heated by the ink heating portion; a main body portion having an ink supply path for inducing ink from an ink retaining portion; and a connecting member having a first bonding surface bonded to the main body portion, and a second bonding surface bonded to the recording element base plate. For this head, the connecting member is formed by material having a weaker stretching strength than that of the recording element base plate. With the structure thus arranged, it is possible to provide an ink jet recording head capable of printing high-quality images at all times without deforming the recording element base plate due to the difference in the bonding temperature of the recording element base plate and room temperature, or due to temperature changes at the time of driving, even if the number of nozzles increases and the recording element base plate is made longer.

摘要： An ink tank has a first containing chamber for containing a negative pressure generating member for retaining liquid and being provided with a atmospheric communication hole to make the negative pressure generating member to be communicative with the air outside; and a second containing chamber communicated with the first containing chamber for retaining liquid directly. For this ink tank, a liquid supply port for supplying liquid to the outside is provided for the first containing chamber, and for the second containing chamber as well. With the structure thus arranged, it becomes possible not only to continue stable consumption of ink in the second containing chamber, but even after ink in the second containing chamber is no longer available, ink in the first containing chamber can be used up to the last. Hence, a highly reliable and stable supply of ink is possible even when the number of nozzles or the driving frequency is increased for printing at higher speed.

摘要： A method for manufacturing an ink jet printing head comprises a step of joining together a base board having ink discharge pressure generating elements, which also forms the bottom of a plurality of ink paths, and a ceiling plate that forms the ceiling portion of the plurality of ink paths in order to provide an ink jet printing head. In this method, either one of the joining portions between the base board and ceiling plate is Si and the other one of them is metal, and after each of the joining portions is irradiated by an energy particle, the base board and the ceiling plate are made in contact and cold joined by the application of cold activation. With the method of manufacture thus provided, it is possible to make the intensity of joint between the ceiling plate and base board firmer so as to eliminate any gaps between them, hence preventing the creation of cross talk phenomenon, and the degradation of quality of printed images as well.
