摘要： A transfer device includes a transfer member and a bias applicator. The transfer member contacts a surface, on which a toner image is borne, of an image bearing body, to form a transfer nip. The bias applicator applies a DC voltage and an AC voltage as transfer bias to transfer the toner image on the image bearing body to a recording sheet in the transfer nip. The bias applicator applies a DC voltage having a same polarity as the DC voltage of the transfer bias and an AC voltage having an amplitude smaller than the AC voltage of the transfer bias or applies the DC voltage having the same polarity as the DC voltage of the transfer bias without applying an AC voltage, when an inter-sheet area that exists on the image bearing body passes through the transfer nip during a continuous image formation period.

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 rotatable image bearing member, a nip forming member, and a power source. The rotatable image bearing member bears a toner image on a surface thereof and rotates. The nip forming member contacts the surface of the image bearing member to form a transfer nip therebetween. The power source applies a transfer bias to the transfer nip to transfer the toner image from the image bearing member onto a recording medium interposed in the transfer nip. The transfer bias includes a superimposed transfer bias in which an alternating current (AC) component is superimposed on a direct current (DC) component and a polarity of the superimposed transfer bias changes with time. A phase difference between an AC voltage and an AC current output from the power source is equal to or less than 0.47 cycles.
