The base pad (241) includes a pressure portion (50), an extension portion (51), and a curved portion (52). The pressure portion (50) presses against the opposed rotary body (22) via the endless belt (21). The extension portion (51) is contiguous to and disposed upstream from the pressure portion (50) in a recording medium conveyance direction. The extension portion (51) does not press against the opposed rotary body (22) via the endless belt (21). The curved portion (52) is disposed upstream from the extension portion (51) in the recording medium conveyance direction and smoothly blends into the extension portion (51). The curved portion (52) does not press against the opposed rotary body (22).
