Abstract: In an ink jet recording apparatus having a recording head, a cap for enclosing the ink discharge port is made of elastic material and is connected via a tube to a pump or waste ink treating member. The cap and tube are guided so that they may move in forward and backward directions with respect to the recording head; deformation of the cap and tube in other directions is prevented.

Abstract: An ink jet apparatus has discharge openings for discharging yellow, cyan, magenta and black inks. Suction recovery in the apparatus is performed using a cap which caps all of the discharge openings collectively. A suction opening is located in the cap closer to the discharge openings for dark (e.g. black) ink than to the discharge openings for light (e.g. yellow) ink. When suction is applied to the cap, ink is drawn from all the discharge openings, and mixing of inks close to discharge openings for light-color inks is minimized.

Abstract: An ink jet recording apparatus has an ink recording region and an electrostatic attraction device. The ink recording region is located at a position spaced from an ink jet recording head. The electrostatic attraction is arranged at an opposite side to a surface of a recording medium to be recorded, in the ink recording region. The has a plurality of first regions and second regions which are alternately distributed. The first regions electrostatically attract the recording medium in the ink recording region relatively strongly and the second regions attract the recording medium relatively weakly. The electrostatic attraction serves to minimize the effects of cockling and that assures stable, high quality recording.
