Black iron-based particles comprise a FeTiO 3 —Fe 2 O 3 solid solution or a mixed composition of a FeTiO 3 —Fe 2 O 3 solid solution and an iron-based oxide having a spinel structure, and having a Ti content of from more than 10.0 atm % to 40.0 atm %, calculated as Ti, based on whole Fe, and a blackness (L* value) of 6 to 13. |
