PROBLEM TO BE SOLVED: To enable recycling and biodegradation by using a decomposable plastic synthesized from saccharide and non-saccharide as a part of the components of an ink-jet head cartridge, an ink tank or an ink tank cartridge. SOLUTION: A decomposable plastic synthesized from saccharide 21 and non-saccharide 22 is used for a part of an ink-jet head cartridge, an ink tank, an ink tank cartridge or a replaceable component. The decomposable plastic comprises a copolymer of the saccharide 21 and the non-saccharide 22 having at least two functional groups reactive with the saccharide 21. The saccharide 21 is a compound containing sugar and a sugar derivative. By the degradation treatment after collection, it can be recycled to the decomposable plastic material, or even if it is abandoned in the environment after collection, it can be degraded naturally to be the compost. |
