Abstract
An ink follower for a writing tool comprises a swollen gel formed from an oil-absorbable resin and a base oil, i.e., a hardly volatile liquid and/or a nonvolatile liquid. The ink follower is arranged in contact with the ink surface of a writing tool such as a pen. A writing tool using the ink follower has excellent impact resistance without causing insufficient following and oil separation with the passage of time and with no occurrence of inconvenience in writing.
