Abstract: PROBLEM TO BE SOLVED: To remove matters adhering to the jet port surface easily through a simple structure by forming a cleaning means of a substantially columnar elastic member absorbing no liquid so that it is deformed elastically upon abutting against a surface including the jet port part. SOLUTION: Matters adhering to a jet port surface 3f, i.e., a recessed bottom face, are removed by a cleaning means employing a substantially tubular hollow wiper blade 2a. The wiper blade 2a is made of a material not subjected to aging, breakage, and the like, including silicon rubber, urethane rubber, HNBR, and the like. A recessed part elongating along a series of jet ports 3g in the center of the head face 3e serves as the jet port face 3f and the series of jet ports 3g are arranged in the jet port face 3f. When a recording head is wiped, the wiper blade 2a is not only contracted but the circular hollow shape thereof is collapsed by an abutting pressure while copying the profile of the recess smoothly. Consequently, the recording head can be wiped surely up the corner of the recess without requiring the work for copying the profile of the recess accurately.

Abstract: PROBLEM TO BE SOLVED: To reduce, to the utmost, a time of contact of a liquid containing impurities with the face of a discharge port and an amount of the liquid in contact therewith, while minimizing consumption of the liquid, and to realize an early and reliable initial operation of recovering suction of a liquid discharge head, by optimizing the conditions of the initial suction recovering operation which is conducted on the occasion of fitting the liquid discharge head. SOLUTION: When the liquid discharge head is fitted, the first suction from a discharge port is conducted on the basis of a first negative pressure curve showing the relation between the negative pressure inside a cap and an elapsed time in a capping state. Then, the second suction from the discharge port is conducted on the basis of a second negative pressure curve whereon the frequency of occurrence of a peak of the negative pressure for a unit time is smaller than that on the first negative pressure curve in the capping state.

Abstract: PROBLEM TO BE SOLVED: To reduce the total amount of metal ions to be added to a color ink to a minimum possible level while reducing bleeding and white haze. SOLUTION: An ink-jet recording head 1 comprises a black ink nozzle row Bk1 for ejecting a black ink as a first ink and a plurality of color ink nozzle rows C1-C3 for ejecting color inks. To the color ink nozzle row C1 with the shortest printing interval with respect to black printing using the black ink nozzle row Bk1, a color ink with the highest mutual reactivity with the black ink is introduced. To the nozzle row C2 with the second shortest printing interval, a color ink with the second highest mutual reactivity is introduced. To the nozzle row C3 with the longest printing interval, a color ink with the lowest mutual reactivity is introduced.

Abstract: PROBLEM TO BE SOLVED: To provide a small-sized ink jet recording apparatus and a recording head, having a mechanism for suppressing the wasteful consumption of ink at the time of recovery operation and sufficiently recovering the state of discharge orifices. SOLUTION: The introducing port communicating with an ink tank is provided to the recording head separately from discharge orifices. At the time of recovery treatment of the discharge orifices, the cap for hermetically closing the discharge orifice surface of the recording head is pressed by a piece to bring the cap and the discharge orifice surface to a close contact state and the piece is further moved to change the volume of the communication part to make the pressure in the cap negative. By this constitution, the ink fixed to the discharge orifices is sucked to be accumulated in the communication part and returned to the ink tank through the introducing port.
