Image forming method with white toner and color toner, and image forming apparatus including annular belt, heating member, and facing member facing said heating member via said annular belt

An image forming apparatus, comprising a fixer that fixes a toner image onto a recording medium,

• the toner image including a white toner image and a color toner image disposed on the white toner image, wherein
• the fixer includes:
• an annular belt;
• a heating member disposed on a side of an inner peripheral surface of the annular belt;
• and
• a facing member disposed on a side of an outer circumferential surface of the annular belt and facing the heating member via the annular belt,
• the fixer nips the recording medium between the annular belt and the facing member and fixes the toner image onto the recording medium, the recording medium being a recording medium on which the toner image is formed, the annular belt being supported by the heating member, and
• the white toner and the color toner satisfy a relationship of a following expression:
• 0.3≤log μ(W110)−log μ(C100)
• where log μ(W110) is a logarithmic value of a viscosity of the white toner at 110° C., and log μ(C100) is a logarithmic value of a viscosity of the color toner at 100° C.
