A toner is provided that comprises a colorant and a binder resin, wherein the binder resin comprises a
polyester resin that is prepared by a
polycondensation reaction in the presence of at least a
titanium-containing catalyst expressed by General Formula (II) or (II), the toner has a
volume average particle
diameter of 2.0 μm to 10.0 μm and a ratio Dv / Dn within a range of 1.00 to 1.40, in which Dv represents a
volume average particle
diameter and Dn represents a number average particle
diameter,Ti(—X)m(-OH)n General Formula (I)O═Ti(—X)p(-OR)q General Formula (II)in General Formulas (I) and (II), X represents a residue of a mono-
alkanolamine of 2 to 12 carbon atoms or a polyalkanolamine from which a
hydrogen atom of one hydroxyl group is removed; other hydroxyl group(s) and still other hydroxyl group(s), within the polyalkanolamine molecule that has a directly bonding Ti atom, may polycondense to form a ring structure; other hydroxyl group(s) and still other hydroxyl group(s) may polycondense intermolecularly to form a repeating structure; and the
polymerization degree is 2 to 5 in a case of forming the repeating structure; R represents one of a
hydrogen atom and
alkyl groups of 1 to 8 carbon atoms that may have 1 to 3
ether bonds; “m” is an integer of 1 to 4; “n” is an integer of 0 to 3; the sum of “m” and “n” is 4; “p” is an integer of 1 or 2; “q” is an integer of 0 or 1; the sum of “p” and “q” is 2; and in a case that “m” and “p” is 2 or more, the respective Xs may be identical or different each other.
