  • Patent number: 10042293
    Abstract: An image forming apparatus includes a transfer power supply and a controller. The controller is configured to execute control for an end-portion voltage that is a DC voltage of a transfer bias at a time of transferring a toner image to an end portion of a recording sheet and a body-portion voltage that is a DC voltage of a transfer bias at a time of transferring a toner image to a body portion on a rear side of an end portion of a recording sheet, such that the end-portion voltage is set to be higher than the body-portion voltage in the DC transfer bias and a value obtained by dividing the end-portion voltage by the body-portion voltage in the superimposed transfer bias is set to be smaller than a value obtained by dividing the end-portion voltage by the body-portion voltage in the DC transfer bias.

The controller switches between a first mode and a second mode according to a predetermined condition. In the first mode, a duty of the transfer bias is a first duty and a width of a transfer nip is a first width. In the second mode, the duty of the transfer bias is a second duty lower than the first duty and the width of the transfer nip is a second width greater than the first width. The duty is (T?Tt)/T×100% where T denotes one cycle of the transfer bias, and Tt denotes a time period, in which the transfer bias is on a transfer-directional side relative to a time-averaged value of the transfer bias, in the one cycle.

  • Patent number: 9720355
    Abstract: An image forming apparatus includes an image bearer, a transfer member, and a power source. The image bearer includes a plurality of layers. The transfer member forms a transfer nip between the image bearer and the transfer member. The power source outputs a transfer bias to transfer a toner image from the image bearer onto a recording sheet in the transfer nip. The transfer bias alternates between a transfer-side bias that causes the toner image to move from the image bearer to the recording sheet, and an opposite-side bias different from the transfer-side bias. A duty ratio of a time period, during which the opposite-side bias is output, relative to one cycle of a waveform, is greater than 50%.
