A control apparatus includes: a driving unit configured to drive a member into rotation; a detection unit configured to detect a torque exerted on the driving unit; and a control unit configured to control the driving unit and the member. The control unit is further configured to: when a state control of the member associated with a change of the torque exerted on the driving unit is performed, determine a change timing of the torque exerted on the driving unit and a value of the torque exerted on the driving unit at the change timing on a basis of a detection result of the detection unit; and determine a start timing of the state control of a case where the state control is again performed on the member on a basis of the change timing and the value of the torque.

Control apparatus for driving a member into rotation and image forming apparatus

An image heating apparatus includes: a rotatable cylindrical belt; a heater, provided inside the belt, for heating the belt; and an overheating preventing element, including a circuit which is opened when abnormal temperature rise occurs, for interrupting electric power supply to the heater. The overheating preventing element is provided at a position, inside the belt, where the overheating preventing element is free from direct heat radiation emitted from said heater.

A sheet feeding apparatus main body for containing sheets in the inside thereof includes: a first cover and a second cover which are openable and closable; and a detecting sensor for detecting an opening and closing of the first cover. The detecting sensor does not detect closing of the first cover when the first cover is closed in a state in which the second cover is opened and detects closing of the first cover when the first cover is closed in a state in which the second cover is closed.
