A toner including at least a binder resin; a colorant; and a charge controlling
agent, in which the binder resin includes at least a polyester resin having a molecular
weight distribution such that components having a molecular weight not greater
than 500 are included in an amount of 4% by weight and at least a peak is present
in a range of from 3,000 to 9,000 when measured by Gel Permeation Chromatography.
In addition, the binder resin does not include a tetrahydrofuran-insoluble compound
and the charge controlling agent is a resin charge controlling agent including
at least units obtained from a monomer including a sulfonate group; an aromatic
monomer including an electron absorption group; and an acrylic ester and/or a methacrylic
ester monomer.
