摘要： An apparatus for image formation comprises a fixing member, a pressing member, a heating member, a sensor, and a controller. The heating member heats at least one of the fixing and pressing members during a heating operation. The sensor senses the surface temperature of at least one of the fixing and pressing members. If the surface temperature sensed by the sensor exceeds a threshold temperature, the controller stops the heating operation of the heating member. If the sensed temperature drops below the threshold temperature, the controller starts the heating operation of the heating member. The controller includes a period measuring unit for measuring the switching period at which the controller switches the starting and stopping of the heating operation of the heating member. The controller restrains the heating of the fixing and pressing members if the switching period exceeds a reference time.

摘要： A developer recovery device is provided with a recovery container that receives and accommodates developer recovered from an image carrier, an agitator member that agitates the developer inside the recovery container, two shafts, to which mutually engageable cams are respectively provided, transmit rotational force to the agitator member, a spring that biases and causes to move one of the cams such that the two cams mutually engage and that causes a shaft connection between the two shafts to join, a torque limiter that carries out joining of the shaft connection, and disjoining of the shaft connection, in which the two cams are caused to move apart to disjoin the shaft connection, and a full-state determination portion that detects a shaft connection disjoined state and, based on the detected disjoined state, determines that the recovery container has become full of developer.
