FIXING DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME

摘要

A fixing device to fix an unfixed image carried on a recording medium includes an endless, rotary fixing member; a heat source to heat the fixing member; an opposed member disposed opposite the fixing member and to form a fixing nip in combination with the fixing member; and a biasing member disposed opposite the opposed member with the fixing member interposed therebetween, to press the fixing member from a back side of the fixing member against the opposed member at the fixing nip; grip portions at which the fixing member and the opposed member contact each other in areas through which the recording medium does not pass, among the fixing nip along a direction perpendicular to a conveyance direction of the recording medium; and a cleaning member to clean an outer circumference of at least one of the grip portions of the fixing member and the opposed member.

主权项

1. A fixing device to fix an unfixed image onto a recording medium, comprising:
an endless, rotary fixing member; a heat source to heat the fixing member; an opposed member disposed opposite the fixing member and configured to form a fixing nip in combination with the fixing member, wherein the opposed member rotates and the fixing member driven by the opposed member rotates so that the recording medium carrying the unfixed image is conveyed to the fixing nip and the unfixed image thereon is fixed onto the recording medium; a biasing member disposed opposite the opposed member with the fixing member interposed therebetween, to press the fixing member from a back side of the fixing member against the opposed member at the fixing nip, wherein the fixing member slides along a contact surface with the biasing member; grip portions of the fixing member and the opposed member at which the fixing member and the opposed member contact each other in areas through which the recording medium does not pass, located among the fixing nip along a direction perpendicular to a conveyance direction of the recording medium; and a cleaning member to clean at least one of the grip portions of the fixing member and the opposed member.
