Abstract

The ink reservoir has a side wall (1), a front end wall (2) having an outlet opening and an intermediate wall (7) which is located opposite the end wall (2) and consists, at least in a partial region, of a membrane which is permeable to air but not permeable to ink, and behind which a space is formed which serves as a pressure compensation chamber (10). In the region of the end wall (2), the ink reservoir has passage openings (5) which are covered by a membrane (6) which is permeable to air but not permeable to liquid. <IMAGE>
