Abstract
An ink container includes a casing, an air vent which is located in the casing, an ink supply opening for supplying ink out of the casing, and an ink absorbing material that is contained in the casing. The ink absorbing material retains ink therein, and has a generally rectangular parallelopipedal shape defined by sides of the ink absorbing material, and also has an ink supply portion for supplying ink to the ink supply opening. The ink absorbing material includes corner portions which are located between adjacent sides of the ink absorbing material. A preventing means prevents complete surface contact between the casing and said ink absorbing material by providing spaces between the casing and ink absorbing material which are in fluid communication with each other with a given space that is adjacent to a particular one of the corner portions that is most remote from the ink supply portion. The air vent is in fluid communication with the spaces.
