Patent ID: 7805087

Claim:
An image forming apparatus comprising: a sheet conveying device configured to convey a sheet along a conveying path; a fixing roller configured to perform thermal fixing on the sheet having unfixed toner; a motor configured to rotationally drive the fixing roller; a first sheet detector disposed downstream from the fixing roller; a second sheet detector provided between the first sheet detector and the fixing roller and where the second sheet detector does not detect the sheet when the sheet is being properly conveyed; and a controller configured to perform a first motor stopping method and a second motor stopping method for stopping the driving of the motor, a deceleration force to decelerate the motor in the first motor stopping method is higher than a deceleration force to decelerate the motor in the second motor stopping method, wherein, when the controller detects that the sheet is jammed on the basis of the first sheet detector not detecting the sheet at a predetermined timing, the controller determines a motor stopping method to select on the basis of a detection result of the second sheet detector.
