Abstract
An image forming apparatus includes an image forming device a fixing device having a fixing nip by wherein in an image forming process of the image forming device, 0<B<ρπL/(30×31/2) is satisfied where L (μm) is a volume average particle size of toner of the unfixed toner image, ρ (g/cm^3) is a density of the toner, B (mg/cm^2) is a maximum toner deposition amount, per unit area, on a predetermined recording paper, wherein the fixing device fixes the toner image while satisfying that, at an outlet of the fixing nip, a viscosity of a toner layer contacting the fixing device is not higher than 1500 (Pa·s), and a viscosity of a toner layer contacting the recording paper is not lower than 3000 (Pa·s).
