Fixing device with support and image forming apparatus incorporating same

摘要

A fixing device (20) includes a support (25) that includes a base (25a) contacting a nip formation assembly (24). An upstream projection (25b1) projects from the base (25a) in a pressurization direction of an opposed rotary body (22) at a position on the base (25a) corresponding to or upstream from an upstream edge (N1) of a fixing nip (N) formed between the opposed rotary body (22) and an endless belt (21) in a recording medium conveyance direction. A downstream projection (25b2) projects from the base (25a) in the pressurization direction of the opposed rotary body (22) at a position on the base (25a) corresponding to or downstream from a downstream edge (N2) of the fixing nip (N) in the recording medium conveyance direction. The downstream projection (25b2) is spaced apart from the upstream projection (25b1) in the recording medium conveyance direction.
