Abstract
An ink container usable for recording heads different in flow rate without being affected by a pigment particle concentration of ink held in an ink supply portion is provided. In correspondence with a size of a filter of a recording head used, ink non-conducting areas are provided to a press-contact member, whereby movement of settled ink remaining in the press-contact member is blocked. As a result, common use of the ink container with respect to the recording heads different in flow rate is realized.
