Abstract

There is provided a hard carbon black having extremely excellent low heat generation properties while keeping high-level abrasion resistance. The hard carbon black has selective properties of the following formula (1): CA < 0.35 x DBP + 2 (1), wherein CA denotes an index calculated from an envelope area and a projected area of an aggregate according to the following formula (2): CA = (envelope area - projected area)/projected area x 100 (2), wherein the envelope area and the projected area of the aggregate are obtained by analyzing a two-dimensional projection image of the aggregate taken with a transmission-type electron microscope; and DBP denotes a DBP absorption.
