Abstract
An image forming apparatus includes an image forming unit that forms an unfixed toner image on a recording material and a fixing unit, 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) 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) of each color in the unfixed toner image on the recording material so as to satisfy the following condition: A<ρπL/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: √(ρπL/90√3A)≦Dot Spread Amount.
