An image forming apparatus includes a transfer member configured to abut against an image carrier for carrying a toner image to form a transfer nip; and a power supply configured to output a bias voltage for transferring the toner image on the image carrier onto a recording medium nipped in the transfer nip. The bias voltage includes a first voltage for transferring the toner image from the image carrier onto the recording medium in a transfer direction and a second voltage having an opposite polarity of the first voltage, the first and the second voltages being alternately output. A time-averaged value of the bias voltage is set to a polarity in the transfer direction and is set in the transfer direction side with respect to a median between a maximum and a minimum of the bias voltage.

An image forming apparatus includes a nip forming member and a transfer bias output device that outputs a transfer bias to form a transfer electric field in a transfer nip between the nip forming member and an intermediate transfer member. Upon transfer of a composite toner image including a particular toner image onto a recording medium in the transfer nip, the transfer bias output device outputs the transfer bias including a first superimposed bias in which a direct current (DC) component is superimposed on an alternating current (AC) component. Upon transfer of the composite toner image without the particular toner image onto the recording medium in the transfer nip, the transfer bias output device outputs one of the transfer bias including a second superimposed bias having a peak-to-peak value of the AC component smaller than that of the first superimposed bias and the transfer bias including only the DC component.

There is provided a photoreceptor cleanerless image forming apparatus capable of decreasing color mixture or an exposure error due to reverse transfer toner an untransferred toner. An image forming apparatus 100 according to the present invention comprises four image forming units 100a, 100b, 100c, and 100d configured to be photoreceptor cleanerless in a 4-drum tandem manner. Each image forming unit includes a photoreceptor 103a, 103b, 103c, or 103d, a charger 105a, 105b, 105c, or 105d, an exposure apparatus 106a, 106b, 106c, or 106d, and a developing apparatus 109a, 109b, 109c, or 109d. When exposure intensities Iy, Ic, Im, and Ik are assumed for exposure sources of the exposure apparatuses in the image forming units which form yellow, magenta, cyan, and black images, respectively, the exposure intensities are configured to satisfy conditions of Ik≧Ic≧Im≧Iy and Ik>Iy. This decreases an exposure error (image hysteresis) in an image formed on paper.

In an image forming apparatus, a determiner determines a target amount of transfer current based on first and second algorithms each representing a relation between an image area rate of a latent image bearer in the vicinity of an exit of a transfer nip and a target amount of transfer current to be provided to a nip creating member. The first algorithm is utilized in a second transfer step when the image area rate falls within a typical range from the lower limit (a %) to the upper limit (b %). The first algorithm decreases the target amount as the image area rate increases within that range.

An apparatus includes: an image carrier; a charger to uniformly charge a surface of the image carrier; an exposing unit to perform write scanning on the image carrier; a developing unit that includes a developer carrier carrying a developer including a toner and that is configured to perform a visible image process on an electrostatic latent image formed on the image carrier; and a transferor to transfer a toner image that has been subjected to the process onto a material. If length Lg of a non-image part directly before an image part in an image carrier moving direction has the relation of Lg≧π·Ds/(Vs/Vp), where Vp and Vs are circumferential velocities of the image carrier and the developer carrier and Ds is a diameter of the developer carrier, suppression of toner attachment on the material is controlled in a predetermined length from an image front end in the direction.
