摘要： Sheets fed out from a sheet feeding portion, which is brought into pressure contact with the sheets by the upward movement of a sheet stacking portion to feed out the sheets, are separated and conveyed one by one while being upwardly curved. During the sheet feeding operation, the sheet stacking portion is sequentially moved up, and when the sheet feeding operation is completed, the sheet stacking portion is moved down. Further, a remaining amount indicating member moved with the upward movement of the sheet stacking portion to indicate the remaining amount of sheets is held at a position before the sheet stacking portion is moved down, by a holding mechanism, when the sheet feeding operation is completed and the sheet stacking portion is moved down.

摘要： This invention is intended to control the amount of power to be supplied to a fusing heater below a maximum applicable current value. The engine controller supplies electricity to both of two heating bodies at the same fixed duty D1. At a phase angle α1 corresponding to the fixed duty D1, pulse signals ON1 and ON2 are issued in response to a ZEROX signal as a trigger. A current value I1 is detected based on a HCRRT signal from the current detection circuit. The engine controller calculates an upper limit of applicable power duty Dlimit based on the detected current value I1, the fixed duty D1 and the preset applicable current value Ilimit. Then, a PI temperature control is performed at a duty below the upper limit duty Dlimit.

摘要： At step S301, since none of conveyance sensors 114, 116 and 121 detect residual paper, a CPU 203 notifies a CPU 201 that it is in a residual paper check start instruction waiting mode. At step S302, since a conveying path sensor 111 in an optional paper feed unit 101 does not detect residual paper, the CPU 202 notifies the CPU 201 that it is in a residual paper check start instruction waiting mode. At step S303, since an inlet sensor 122 of an optional paper output unit 103 does not detect residual paper, the CPU 204 notifies the CPU 201 that it is in a residual paper check start instruction waiting mode. After confirming that all the units are in the waiting mode, the CPU 201 issues a residual paper check start instruction to all the units simultaneously to improve usability by reducing initializing time.

摘要： In an image forming apparatus having a toner container, the remaining amount of toner is detected by measuring a capacitance caused by a toner detector member in the toner container. It is determined whether the measured capacitance falls within a predetermined range. If it is determined that the measured capacitance falls not within the predetermined range, the measured capacitance is not used in the detection of the remaining amount of toner. The present invention thus provides an image forming apparatus reliable in the detection of toner, and a method of controlling the apparatus.

摘要： An image forming system including an image forming apparatus and a sheet feeding apparatus. The system includes: a first conveying unit conveying to the image forming apparatus a recording material; a second conveying unit conveying to an image forming unit of the image forming apparatus the recording material; a detector detecting a recording material type while the second conveying unit halts conveying the recording material; a first controller, based on detection by the detector, determining a speed for conveying the recording material to the image forming unit, and conveying the recording material at the conveying speed; and a second controller controlling recording material conveying speeds of the first conveying unit. Before the recording material reaches the second conveying unit, the second controller maintains a first conveying speed, and after the recording material reaches the second convey unit, maintains a second conveying speed determined by the first control unit.
