When a roller (35) faces a concave portion (39) of an eccentric cam (37), a pressure roller (26) is brought into press contact with a fixing roller (25) at the spring pressure of a lower compression spring (32) via a lever (34) and an arm member (29). When the roller (35) faces a maximum radius part (R1), the pressure roller (26) moves in a direction separating from the fixing roller (25) via the lever (34) and the arm member (29) against the spring pressure of the lower compression spring (32). |
