摘要： An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developing unit that develops the electrostatic latent image using a toner; an intermediate transfer body onto which toner image is transferred; a secondary transfer member that comes in contact with a surface of the intermediate transfer body; a power supply that outputs a voltage for transferring the toner image on the intermediate transfer body onto a recording member; and a protective agent supply unit that applies a protective agent including zinc stearate and boron nitride onto a surface of the image carrier. The voltage is alternatively switched in a transfer direction and an opposite direction. The voltage in the transfer direction enables transfer of the toner image from the intermediate transfer body to the recording member, and the voltage in the opposite direction has polarity opposite to polarity of the voltage in the transfer direction.

摘要： An image forming apparatus includes an image bearing member to bear a toner image on a surface thereof, a transfer device to transfer the toner image onto a recording medium, and a transfer bias power source to apply to the transfer device a superimposed transfer bias in which an alternating current (AC) component is superimposed on a direct current (DC) component in a superimposed transfer mode to transfer the toner image. The superimposed transfer bias has a waveform in which a first polarity in a direction of transferring the toner image onto the recording medium and a second polarity opposite the first polarity switch alternately. The superimposed transfer bias is output such that a standard value of each of the DC component and the AC component is multiplied by a respective correction ratio, and the correction ratio of the DC component is different from that of the AC component.

摘要： An image forming apparatus includes a toner forced consumption control unit that performs toner forced consumption control in which toner in a developing unit is forcibly consumed when a certain condition to perform the toner forced consumption control is met. The certain condition to perform the toner forced consumption control includes a specific performance condition that a transfer bias switching condition to switch a transfer bias to a superimposed transfer bias in which an alternating current component is superimposed on a direct current component, from a direct current transfer bias is met. When the specific performance condition is met, the toner forced consumption control unit performs preliminary toner forced consumption control in which the toner forced consumption control is performed before an image forming operation using the superimposed transfer bias is started.

摘要： An image forming apparatus includes a transfer bias output device and an information receiving device. The transfer bias output device outputs a transfer bias including a superimposed bias composed of an AC bias superimposed on a DC bias to form a transfer electric field in a transfer nip between an image bearing member bearing a toner image and a nip forming member, to transfer the toner image onto a recording medium in the transfer nip. A controller operatively connected to the information receiving device and the transfer bias output device causes the transfer bias output device to change a target output of a peak-to-peak voltage of the AC bias based on information received by the information receiving device that affects transfer of the toner image and to reduce a target output of the DC bias as the target output value of the peak-to-peak voltage of the AC bias increases.
