A fixing device includes a fixing member, a pressing member, and a driving unit. The fixing member and the pressing member define a nip portion where a toner image is fixed on a recording material. The driving unit is provided to the fixing member and the pressing member to individually control linear velocities of outer circumferential surfaces of the fixing member and the pressing member. In feed mode in which the outer circumferential surfaces sandwich the recording material to fix the image on the recording material, the driving unit drives the fixing member and the pressing member such that the outer circumferential surfaces move at individual linear velocities to reduce a feed speed difference between front and rear surfaces of the recording material. In non-feed mode, the driving unit drives either one of the fixing member and the pressing member such that another member is driven by the one member. |
