Patent ID: 8837971

Claim:
An image forming apparatus, comprising: an image forming unit that forms an unfixed toner image, in which toners of a plurality of colors are stacked, on a recording material; and a fixing unit that fixes the unfixed toner image formed on the recording material to the recording material by heating and pressing the unfixed toner image in a fixing nip portion, wherein, in a case where an image is formed by using the toners of the plurality of colors, when a specific gravity of the toners is ρ (g/cm 3 ) and a weight average particle diameter of the toners is L (μm), the image forming unit sets a maximum laid-on amount A (mg/cm 2 ) of each color in the unfixed toner image on the recording material so as to satisfy the following condition: A < ρ ⁢ ⁢ π ⁢ ⁢ L 30 ⁢ 3 , and wherein the fixing unit fixes the unfixed toner image to the recording material so that a dot spread amount (μm) of the toner image satisfies the following condition: ρ ⁢ ⁢ π ⁢ ⁢ L 3 90 ⁢ 3 · A ≤ Dot ⁢ ⁢ Spread ⁢ ⁢ Amount .
