<p>An ink tank with a high volume efficiency and a printing apparatus which are capable of completely using up ink stored in the ink tank. A meniscus holding force (Pm1) of a non-compressed portion (22b) of an ink guide member (22) is set higher than an initial ink-storage-portion negative pressure (P1), and lower than a used-up ink-storage-portion negative pressure (P2). In addition, a meniscus holding force (Pm2) caused under compression is set stronger than the used-up ink-storage-portion negative pressure (P2), and weaker than a meniscus holding force (Phf) of a head filter (50).</p>
