Abstract
A disclosed fixing device fixes unfixed toner onto a recording sheet with the use of toner fixing liquid including a softening agent for softening toner. The fixing device includes a sprayer configured to spray the toner fixing liquid as liquid droplets and a liquid droplet charging unit configured to apply an electric charge to the sprayed liquid droplets. The sprayer sprays the liquid droplets onto the unfixed toner placed on the recording sheet. The liquid droplet charging unit applies, to the sprayed liquid droplets, an electric charge of an electric charge polarity that is the same as that of the unfixed toner.
