Fixing device, image forming apparatus including the same, and method for controlling the fixing device

A fixing device includes a heating rotating member (11), a pressing rotating member (12), a motor (7), a fixing pressure adjustment mechanism (6), a control section (50), a motor drive section (8), a detecting member (71), and a stop control circuit (9). The heating rotating member (11) heats a paper sheet. The pressing rotating member (12) is pressed to the heating rotating member (11). The motor (7) can rotate in both forward and backward directions. The fixing pressure adjustment mechanism (6) moves a rotating member to be moved between first and second positions. The control section (50) includes a control device (501), issues an instruction of voltage to be applied to the motor (7). The motor drive section (8) controls the voltage to be applied to the motor (7). The detecting member (71) detects that the rotating member to be moved reaches the first position. The stop control circuit (9) stops the motor (7) without software control when the rotating member to be moved reaches the first position.
