摘要:
An ink cartridge (3) including an ink reservoir portion having a porous member (37) for storing ink and an ink supply portion (39) has an ink inducing element (47) disposed between the ink reservoir portion and the ink supply portion (39). The ink inducing element (47) is made of bundle of fibers in which each fiber is disposed in parallel to the direction of ink supplying from the ink reservoir to the ink supply portion (39), and one end of the ink inducing element (47) is press-touched to the porous member (37).

A liquid discharging head includes a discharge port and a liquid passage provided with bubble-generating means and a movable member. The liquid passage has one side which is closed, and one side which communicates with the discharge port and with a liquid supply port. The movable member has a free end on the closed side of the liquid passage and a fulcrum on the other side. The bubble-generating means is disposed on a wall of the liquid passage facing the free end of the movable member and facing a wall in which the liquid supply port is provided. The movable member is separated from the discharge port by a gap in the liquid passage corresponding to the bubble-generating means. The projected area of the movable member on the liquid supply port is larger than the opening area of the liquid supply port.

A recording head includes a liquid ejecting outlet, a liquid passage communicating with the ejection outlet, and a heat generating resistor for supplying heat to the liquid in a heat acting portion in the liquid to create a bubble in the liquid passage to eject the liquid through the ejection outlet. A cross-sectional area of the liquid passage increases from the heat acting zone toward the ejection outlet, and this improves performance while also improving head durability.

An air communicating hole and an opening circular in cross section are formed in the wall portions of the housing of the ink container. On the inner wall portion surrounding the opening is formed an ink inductive portion which is shaped in the form of an almost solid circular cylinder. The projected end of the ink inductive portion is provided with a cartridge filter as a first filter that forms a boundary with the porous material that works as an ink holding means. The ink inductive portion is virtually solid as a whole and has at least one fine hole formed in the solid portion in such a way that it extends longitudinally to communicate the opening to the interior of the housing where the porous material is installed. At the end of the solid portion of the ink inductive portion is formed a recess as a bubble removing means that removes air bubbles from ink being supplied to the ink jet recording head by retaining the bubbles in the recess.

A transfer recording medium comprising a substrate and a distributed layer of image forming elements, and an image forming method using the recording medium are provided. The distributed layer comprises first and second image forming elements. The first image forming elements comprise at least two species of different coloring characteristics which are capable of decreasing their transferabilities when provided with at light and heat energy under respectively prescribed at least two energy application conditions corresponding to the coloring characteristics. The second image forming element is capable of decreasing its transferability under any one of the at least two energy application conditions.
