摘要： An image forming apparatus includes an electrophotographic imaging unit, a fixing unit, a conveyance unit, and a guide assembly. The electrophotographic imaging unit forms a toner image on a recording medium for forwarding to a media conveyance path. The fixing unit is disposed in the conveyance path to fix the toner image in place on the recording medium through a fixing nip. The conveyance unit is disposed downstream of the fixing unit along the conveyance path to forward the recording medium from the fixing nip. The guide assembly is disposed between the fixing unit and the conveyance unit along the conveyance path to guide the recording medium therethrough. The guide assembly includes a pair of first and second media guide members to form a tapered passageway therebetween to pass the recording medium from the fixing nip into the conveyance unit.
摘要翻译：图像形成装置包括电子照相成像单元，定影单元，输送单元和引导组件。电子照相成像单元在记录介质上形成调色剂图像，以转发到介质传送路径。定影单元设置在输送路径中，以通过定影辊隙将调色剂图像定位在记录介质上的适当位置。传送单元沿着传送路径设置在定影单元的下游，以将定影辊隙的记录介质转送。引导组件沿着传送路径设置在定影单元和输送单元之间，以引导记录介质通过。引导组件包括一对第一和第二介质引导构件，以在其间形成锥形通道，以将记录介质从定影辊隙传递到传送单元中。

摘要： A media stripper mechanism includes a stripping member. The stripping member has a stripping edge extending in an axial, longitudinal direction of the rotary member for contacting the recording medium upon exiting the nip, and a guide surface extending from the stripping edge for guiding the recording medium after stripping from the rotary member. The guide surface exhibits a maximum height roughness Rz of approximately 10 to 18 micrometers.
