Abstract:
An image forming apparatus includes a charger, a photoconductor, a charging high-voltage power supply, and circuitry. The charging high-voltage power supply supplies a charging bias to the charger and generates an output value feedback voltage representing a voltage value corresponding to an output current value from the charger to the photoconductor. The circuitry extracts a minimum value of the output value feedback voltage based on the output value feedback voltage generated in a given time. The circuitry calculates a maximum gap value between the charger and the photoconductor based on the minimum value. The circuitry calculates an AC voltage value based on the maximum gap value. The circuitry adds the AC voltage value to a DC voltage value to generate and transmit an output value control signal to the charging high-voltage power supply, to cause the charging high-voltage power supply to adjust the charging bias.

Claim (Index 13):
A non-transitory, computer-readable storage medium storing computer-readable program code that causes a processor to perform a method for forming an image in an image forming apparatus, the image forming apparatus including a charger, a photoconductor, and a charging high-voltage power supply, the method comprising:\n extracting a minimum value of an output value feedback voltage based on the output value feedback voltage generated by the charging high-voltage power supply in a given time, the output value feedback voltage representing a voltage value corresponding to an output current value, the output current value being a value of an electric current output from the charger to the photoconductor, the photoconductor having an outer circumferential surface facing the charger via a gap; calculating a maximum gap value based on the minimum value of the output value feedback voltage extracted, the maximum gap value being a value of a maximum gap distance between the charger and the photoconductor; calculating an alternating current voltage value based on the maximum gap value calculated; adding the alternating current voltage value calculated to a direct current voltage value to generate an output value control signal; and transmitting the output value control signal to the charging high-voltage power supply to cause the charging high-voltage power supply to adjust and supply a charging bias to the charger, the charging bias including a direct current voltage and an alternating current voltage superimposed on the direct current voltage.
