摘要： An image forming apparatus includes a transfer device to transfer a toner image from an image bearing member onto a recording medium, disposed opposite the image bearing member, a transfer bias power source to apply, between the image bearing member and the transfer device, a superimposed transfer bias in which a direct current (DC) component and an alternative current (AC) component are superimposed to transfer the toner image borne on the image bearing member to the recording medium, and a controller to change the superimposed bias that the transfer bias power source applies. The controller changes the levels of the DC component and the AC component of the superimposed transfer bias in a color mode from that in a monochrome mode to secure a return electric field in the superimposed transfer bias by which the toner is returned from the recording medium to the image bearing member.

摘要： An image forming apparatus includes an image bearing member to bear a toner image charged with a predetermined polarity, and a power source to apply a bias to a transfer portion to transfer the toner image from the image bearing member to a recording medium, a polarity of the bias being changed alternately. The toner image formed with toner of a plurality of colors is transferred in a color mode and the toner image formed with toner of a single color is transferred in a monochrome mode. The bias includes a peak voltage with a polarity that returns toner from the recording medium to the image bearing member. An absolute value of the peak voltage in the color mode is equal to or greater than an absolute value of the peak voltage in the monochrome mode.

The image bearing member defines an image bearing surface on which a toner image is created. The pair of opposed transfer members is disposed opposite each other via the image bearing member to form a transfer nip therebetween through which a recording medium is passed. One of the transfer members defines a first electrode to which a first electrical bias is applied. The media separator defines a second electrode downstream from the transfer nip to which a second electrical bias is applied. The electrical bias applicator includes a power supply connectable with each of the first and second electrodes to supply the first electrical bias to the first electrode and the second electrical bias to the second electrode.

摘要： An image forming apparatus includes a belt-shaped image bearer; a transfer device disposed opposing to the image bearer; an opposed device disposed opposing to the transfer device; and a transfer bias power source. The image bearer is disposed along an outer circumferential surface of the transfer device at at least one of an upstream side and a downstream side of the transfer portion in a direction of conveyance of the recording medium. The transfer bias power source cyclically alternates the transfer bias applied to the transfer portion, between a transfer directional bias in a transfer direction to transfer the toner image from the image bearer onto the recording medium and a reverse directional bias in a reverse direction of the transfer direction. The transfer bias power source applies the reverse directional bias during a time period longer than 50% of one cycle of the applied transfer bias in the one cycle.

摘要： 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%.

摘要： An image forming apparatus, including an image bearer configured to bear a toner image; a transfer device disposed opposing to the image bearer; and a transfer bias power source. The transfer bias power source is configured to output a transfer bias to transfer the toner image onto a recording medium. The transfer bias is a superimposed bias that cyclically alternates between a transfer-directional bias to transfer the toner image from the image bearer onto the recording medium and an opposite-directional bias in an opposite direction of the transfer direction. A ratio of a time period of application of the opposite-directional bias to a total time period of one cycle of the output transfer bias is greater than 50%. The transfer bias power source changes a value of a direct current voltage in the superimposed bias according to a linear velocity of the image bearer.
