Abstract
A toner, including: a colorant; and a binder resin, wherein a spreadability of the toner under a non-pressurized condition is 1.20 to 2.50, wherein a common logarithm of a storage modulus at 100° C. (G') of the toner is 4.0 [log Pa] to 5.0 [log Pa], and wherein a ratio of a loss modulus at 100° C. (G″) to the storage modulus at 100° C. (G′) of the toner (G″/G′=tan δ) is 1.1 to 2.2.
