An ink jet recording apparatus comprising: an ink absorption body; an ink tank using an ink absorption body; an ink jet cartridge including an ink jet recording head and an ink tank integrally; a method of manufacturing an ink tank; Ink jet recording apparatus

摘要

The ink absorption body of the present invention is housed inside the housing of the ink tank and can hold the ink. The ink absorbing member is composed of a fiber material having an outer surface equivalent to or corresponding to the inner surface of the housing and obtained by compressing the fiber body and thermally molding at least one surface of the fiber body. The ink tank is composed of an ink absorption body and a housing. The ink jet cartridge is composed of an ink tank and a print head. A method of manufacturing an ink tank of the present invention comprises a first molding step of forming a continuous fiber aggregate having elasticity such as a rod or a plate shape, a step of cutting the formed fiber aggregate to form a fiber body, A second molding step of compressing and thermally molding the fibrous body so as to have an outer surface corresponding to an inner shape of the housing to form an ink absorbing body; and inserting the ink absorbing body into the housing.
