摘要： A method of forming an electrostatic latent image includes printing operation and toner recovering operation. The printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The remaining bit data of the received video signal, which are not converted into the first signal are converted into a second signal representing another data sequence corresponding to the resolution of an LED head. The LED head includes a resolution conversion circuit which converts the video data into the first signal and the second signal. The signals are stored in a shift register having a plurality of line buffers. The first signal is printed on a basic raster line and the second signal is printed on an additional raster line. An LED head drive energy with which basic raster lines are printed and another LED head drive energy with which additional raster lines are printed are set independently of each other.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The first signal is transmitted to the LED head in the form of a real printing data signal that is to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing another data sequence, and then stored in a line buffer. The second signal stored in the line buffer is transmitted to the LED head in the form of a real printing data signal that is to be printed on an additional raster line in synchronism with an additional line timing signal. The LED head drive energy with which the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other.

摘要： An inductor 6 accumulates an energy therein or releases the accumulated energy according to the state of a main switch element 10 being turned ON/OFF. When the inductor 6 releases an energy, if a sub-switch element 12 is in the ON state, a current is passed through a circuit downstream of the sub-switch element 12, thereby increasing an output voltage VO1. The sub-switch element 12 is a P-channel MOS transistor, and a sub-switch control circuit 18 outputs a control signal VCT1 for the sub-switch element 12. A level shift circuit 19 receives an output-side potential VP of the inductor 6, and outputs, as a control signal VG1 applied to the gate of the sub-switch element 12, the potential VP if the control signal VCT1 is at the L level or a potential (VP-VM) lower than the potential VP if the control signal VCT1 is at the H level. Thus, the output voltage of the DC-DC converter can be made precisely equal to the target voltage.

摘要： A composite MOS transistor device for a semiconductor integrated circuit includes at least a pair of MOS transistors, or first and second MOS transistors, placed on the same board. The first and second MOS transistors are made up of first and second groups of equally divided transistors with an equal gate width, respectively. These divided transistors are arranged in parallel to each other in the gate longitudinal direction. The divided transistors of these groups are arranged such that the sum of coordinates of respective gates, measured from a centerline, is equalized between these groups along the gate longitudinal direction. Since the sum of errors of respective gates along the length thereof becomes zero in each group of divided transistors, the current difference between the two MOS transistors can be eliminated. Accordingly, in forming a differential amplifier or a current mirror circuit using this MOS transistor pair, high current gain can be obtained while maintaining an adequate balance in output current.

摘要： When an electrophotographic printer is manufactured, the initial electrical resistance of its transfer roller is measured and a corresponding value is stored in a memory device in the printer. During operation, the printer's control program estimates the resistance of the transfer roller from the stored value, taking aging into account, then measures the actual resistance of the transfer roller, and infers ambient conditions from the difference between the estimated and actual resistance values. The electrophotographic printer is controlled according to the inferred ambient conditions.
