Abstract

A fixing device includes a rotary fuser member, a rotary pressure member, a first media stripper, and a second media stripper. The rotary fuser member is subjected to heating. The rotary pressure member is pressed against the fuser member to form a fixing nip therebetween through which a recording medium is passed in a media conveyance direction under heat and pressure as the fuser and pressure members rotate together. The first media stripper includes at least one pneumatic nozzle disposed adjacent to the fuser member to direct compressed gas toward the fixing nip along the fuser member for stripping the recording medium from the fuser member. The second media stripper includes at least one contact finger disposed in contact with the pressure member to slide against the pressure member during rotation for stripping the recording medium from the pressure member.

Description

technical field [0001] The present invention relates to a thermal fixing device for fixing a toner image on paper by applying heat and pressure. Background technique [0002] Conventionally, in an image forming apparatus, as a device for fixing a toner image transferred to a recording medium such as paper (hereinafter, abbreviated as "paper"), the following thermal fixing device is widely used: a fixing member heated by a heat source (for example, a fixing roller) and a pressing member (for example, a pressure roller) that pressurizes the fixing member form a nip portion, and the unfixed toner image is sandwiched, conveyed and placed while being heated and pressurized by the nip portion. Thermal fixing devices for fixing toner images on paper are known. [0003] A belt fixing device using an endless fixing belt as a fixing member is also known. The fixing belt has a small heat capacity, so that the heating time can be shortened, and energy saving is good. [0004] In the t...
