Abstract
An ink follower for a writing tool arranged in close contact with an ink surface of a terminal portion of an ink reservoir opposite to a writing tip portion comprises a swollen gel formed from an oil-absorbable resin, a base oil of polybutene, and an alkyl-modified silicone oil compatible with the polybutene. The ink follower exhibits improved impact resistance without causing insufficient ink following and oil separation.
