Abstract:
A fixing device includes a fixing unit and a gloss equalizing unit. The fixing unit is disposed in a media conveyance path to fix a toner image on a recording medium conveyed therethrough. The fixing unit includes a rotary fuser member, a rotary pressure member, and a media stripper. The fuser member is subjected to heating. The rotary pressure member is pressed against the fuser member to form a fixing nip therebetween. The media stripper is held in contact with the pressure member to allow the recording medium to separate from the pressure member. The gloss equalizing unit is disposed downstream from the fixing unit along the media conveyance path. The gloss equalizing unit includes a pair of first and second rotary glossing rollers, at least one of which is heated and at least one of which is pressed against the other to form a gloss equalizing nip therebetween.
