Image forming apparatus

摘要

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/cm3) and a weight average particle diameter of the toners is L (μm), the image forming unit sets a maximum laid-on amount A (mg/cm2) 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: √(ρπL3/90√3A)≦Dot Spread Amount.

1. 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/cm3) and a weight average particle diameter of the toners is L (μm), the image forming unit sets a maximum laid-on amount A (mg/cm2) of each color in the unfixed toner image on the recording material so as to satisfy the following condition:A<ρ⁢⁢π⁢⁢L30⁢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⁢⁢L390⁢3·A≤Dot⁢⁢Spread⁢⁢Amount.
