[PROBLEMS] To express black of a free hue, which is possible with blue-black, purple-black, or jet-black black, which has been difficult to express in the past, with excellent blackness, high heat resistance, and volume resistivity. The present invention provides aniline black particles that are high and have excellent dispersibility. SOLUTION: Hydrophobic degree by powder wettability test is 5 to 80% by volume, and one or more treatment agents selected from alkylamine, vinyl alkyl ketone, fatty acid and silane are 0.1 to 60%.
