Fixing unit and image forming apparatus including the same

摘要

A fixing unit includes: a fixing member which defines a fixing nip, where the fixing member fixes a toner image transferred onto a recording medium by applying heat and pressure to the toner image on the recording medium, and the recording medium passes through the fixing nip; a housing in which the fixing member is disposed, where the housing includes an entrance part, via which the recording medium enters therein, and a discharge part, via which the recording medium is discharged therefrom; and a blocking part disposed on the housing and toward an image surface of the recording medium to which the toner image is transferred, where the blocking part blocks nanodusts, which are generated while the toner image is being fixed to the recording medium, from being discharged to an outside of the housing.
