An image forming apparatus capable of accelerating energy saving, downsizing, and simplification of an image forming apparatus, and having no adverse effect on toner fluidity, charging stability, durability, and productivity. The present invention provides a developing toner having excellent characteristics in high-temperature low-temperature fixing property, anti-offset property, and fixing / separating property, and particularly improved in developing property in a high humidity environment. In a wettability test for a mixed solvent of methanol and water, which contains at least a polyester resin, a polyolefin-grafted vinyl resin, a hydrocarbon wax, and a magnetic iron oxide and is measured at a transmittance of light having a wavelength of 780 nm, A magnetic toner having a methanol concentration of 45 to 65% by volume at a transmittance of 80% and a methanol concentration of 45 to 65% by volume at a transmittance of 10%.
