摘要： Disclosed is a heat fusing apparatus for thermally fusing toner that has been transferred to a printing medium from a toner image formed on an image bearing member using an electrophotographic process. Temperature is detected at the surface of a heating element or in the vicinity thereof. If control is performed so as to interrupt supply of power to the heating element based upon result of comparing the detected temperature and a reference value, the amount of current that flows into the heating element is detected and the reference value is changed over in accordance with the result of detection. Further, a pressure roller, which is a rotation member placed opposite the heating element, presses the printing medium against the heating element and transports the printing medium. The state of rotation of the roller is detected and the reference value is changed over in accordance with the result of detection. The apparatus prevents, without malfunction at the time of normal operation, the occurrence of a situation in which the entire fusing apparatus and peripheral devices must be repaired or replaced owing to overheating, and minimizes apparatus damage to thereby minimize the cost of replacement parts and service cost.

摘要： An image forming apparatus is provided which is capable of reliably preventing a recording sheet wound around a roller member from being further wound around the roller member even when the power supply of the image forming apparatus is turned on/off while the recording sheet is wound around the roller member. A high voltage power supply section applies voltage to feeding brushes disposed in contact with the surface of a pressurizing roller having an electrically conductive surface. A winding sensor is disposed in contact with the surface of the pressurizing roller and is located in a sheet passing area of the pressurizing roller. A CPU provides control such that the pressurizing roller is inhibited from being driven when it determines that the recording sheet is caught between the pressurizing roller and the winding sensor according the result of comparison between the output voltage from the winding sensor and detected voltage of the feeding brushes.

摘要： An image forming apparatus includes an image bearing member and a charge member for electrically charging the image bearing member while contacting the image bearing member. An oscillating voltage, including a component of AC voltage, is applied to the charge member. A first detector detects an average of the AC current applied to the charge member. A second detector detects a value of the AC current corresponding to a peak of the AC voltage. A controller effects control such that when a detected current value is smaller than a first predetermined value, the detected current value of the first detector is at the first predetermined value, and when the detected current value of the first detector is larger than the first predetermined value, a current value of the second detector is at a second predetermined value.

摘要： A stamp unit capable of opening an ink pack position between a grip member and a holder member for supplying ink to the stamp material easily in one step. To supply ink to the stamp material, the grip member is pressed downwardly with the ink pack located in the holder member. The ink pack in the holder member is pressed between a thick paper plate and a cutting rib to be opened. Ink from an ink pack flows downwardly through ink holes to be supplied to the stamp material. When the ink runs low, it can be replenished by the simple process of replacing the ink pack.
