Abstract: An ink absorbing body stores an ink injected into an ink tank for an ink-jet with capillary force between fiber. On a surface of said fiber before filling the ink, a surfactant is deposited within a range of 0.002 to 0.2wt% relative to a weight of the ink or in a range of 0.01 to 0.5wt% relative to a weight of the fiber.

Abstract: A liquid container comprises an inner wall (102) that forms the liquid containing portion to contain liquid therein; an outer wall (101) that forms the container to contain the liquid containing portion therein; and a liquid supply portion for supplying liquid from the liquid containing portion to the outside. Then, the inner wall is arranged to be a member to generate negative pressure in the liquid containing portion by being deformed following the leading-out of the liquid, and also, formed by the material having an elastic modulus change of 25% or less against the temperature change of use environment. With the liquid container thus structured, it is possible to implement the stable supply of liquid by stabilizing the characteristic of negative pressure in the liquid containing portion thereof irrespective of the temperature changes of use environments.

Abstract: A forming method for a fiber aggregate in which fibers are heated to be welded with each other includes a heating step of applying heated air in an upward direction to a bottom of a block of the fibers to pass the heated air therethrough and to cause the block of fibers to float, wherein at least parts of fibers are melted while the block of the fibers float; a compression step of compressing substantially in a vertical direction the heated block of fibers to a desired thickness; and a cooling step of cooling the compressed block of fibers to solidify melted portions of the fibers at portions where the fibers intersect each other.
