Abstract A toner including inorganic particles, wherein the inorganic particles include a fluorine-containing alumina, and the toner satisfies both Formula (1) below and Formula (2) below: 2.7≤X1/X2≤5.5 . . . Formula (1); and 2.1≤X1≤3.0 . . . Formula (2) where X1 denotes a concentration of aluminum in the toner and X2 denotes a concentration of fluorine in the toner, and the concentration of aluminum and the concentration of fluorine are determined through an X-ray photoelectron spectroscopic analysis method.
