Resin or rubber which contains a hydrogen ion releasing additive is used for a member of the apparatus with which ink for ink jet recording comes in contact. The content of the additive in the material is not less than 0.001% by mass and not more than 0.1% by mass. The additive includes at least an acid, a ketone, and a functional group of ester each of which exhibits acidic properties.
