Abstract
Official abstract text for this publication.
The fixing device includes a nip formation assembly partially pressing against an opposed rotary body via an endless belt to form a fixing nip between the endless belt and the opposed rotary body. The nip formation assembly includes a base pad defining the fixing nip and including a pressure portion, an extension portion, and a curved portion. The pressure portion presses against the opposed rotary body via the endless belt. The extension portion is contiguous to and disposed upstream from the pressure portion in a recording medium conveyance direction. The extension portion does not press against the opposed rotary body via the endless belt. The curved portion is disposed upstream from the extension portion in the recording medium conveyance direction and smoothly blends into the extension portion. The curved portion does not press against the opposed rotary body.
