Patent ID: 7241546

Claim:
A toner comprising toner particles containing at least a binder resin and a colorant, and inorganic fine particles, wherein; the toner particles have a shape factor SF-1 of from 100 or more to less than 130; the toner has a storage elastic modulus at 140° C., G′ (140° C.), of from 2.0×10 3 dN/m 2 or more to less than 2.0×10 4 dN/m 2 ; the toner comes to have a viscosity of 1.0×10 3 Pa·s according to a flow tester heating method at a temperature of from 115° C. or more to less than 130° C.; and where a wettability of the toner to a methanol/water mixed solvent is measured as transmittance of 780 nm wavelength light, the methanol concentration at the time the transmittance is 50% is within the range of from 30% by volume to 60% by volume.
