摘要

The ink absorber of the present invention is housed inside the housing of the ink tank and can hold ink. The ink absorber has an outer surface which is the same as or corresponds to the shape of the inner surface of the housing and is composed of a fiber material obtained by compressing the fiber body and heat forming at least one surface of the fiber body. The ink tank is composed of an absorber and a housing. An ink jet cartridge consists of an ink tank and a print head. The method of manufacturing an ink tank of the present invention comprises the steps of forming a continuous fiber assembly having elasticity in the shape of a rod or plate, cutting the molded fiber assembly to form a fiber body, and the fiber body And forming an ink absorber by compressing and heating the fiber body so that an outer surface corresponding to the inner shape of the housing is provided in the housing, and inserting the ink absorber into the inside of the housing.
