Abstract: An rotation angle of a crank arm is calculated on the basis of a period of time in which a recording material is detected or a period of time in which the recording material is not detected and an end position of the recording material is calculated from the calculated rotation angle, so that detection of the end position of the recording material can be started regardless of a stop position of a sensor and the end position of the recording material can be accurately detected without using a dedicated drive source or member to reciprocate the sensor.

Abstract: An image forming apparatus comprises a developer carrier (101) for developing an electrostatic latent image by supplying an image carrier with developer inside a developer container (100); an electrode member (104) opposing the developer carrier (101) via a space accommodating the developer; an inverter (301); a transformer (302) for transforming an AC voltage from the inverter (301); a rectifying circuit (303) for rectifying the output of the transformer and generating a DC voltage for image formation; a DC voltage applying unit (306) for applying the AC voltage, which is output from the transformer, to the electrode member (104); and a developer remaining-amount detection unit (305) for detecting amount of developer remaining inside the developer container (100) based upon electrostatic capacitance between the developer carrier (101) and electrode member (104).

Abstract: The non-sheet-feeding portion temperature rise is reduced during warm-up operation of an image heating apparatus, the time needed for the warm-up operation is reduced, and the accuracy of the image fixing operation is improved. When a CPU determines that a temperature detected by an end portion thermistor is higher than a temperature detected by a center portion thermistor, the CPU controls the temperature of a fixing heater based on a detection result of the end portion thermistor. When the CPU determines that the temperature detected by the end portion thermistor is equal to or less than the temperature detected by the center portion thermistor, the CPU controls the temperature of the fixing heater based on a detection result of the center portion thermistor.
