摘要： [Problem to be solved] To provide an image forming apparatus for suppressing formations of white spots and achieving high quality images, while obtaining sufficient image densities in both of the recessed parts and the projected parts of a recording medium surface.[Solution] An image forming apparatus includes a transfer member 36 that abuts against a surface of an image carrier carrying a toner image and forms a transfer nip, and a power supply 39 that outputs a voltage (transfer bias) for causing the toner image on the image carrier to be transferred onto a recording medium P nipped in the transfer nip. The voltage is switched alternatingly between a transfer direction voltage for causing the toner image to be transferred from the image carrier onto the recording medium and a voltage having an opposite polarity of the transfer direction voltage when the toner image on the image carrier is to be transferred onto the recording medium. A time-averaged value (Vave) of the voltage is set to a transfer direction polarity that causes the toner image to be transferred from the image carrier onto the recording medium, and is set more in the transfer direction than a median voltage (Voff) between a maximum and a minimum of the voltage.

When constant current control is conducted at a timing other than when the toner image is being transferred from the image carrying member to the recording medium, a detection bias voltage at the transfer nip is detected, and the voltage of at least one of the DC component and the AC component is controlled based on the detected detection bias voltage.

摘要： An image forming method includes detecting a toner degradation state by detecting an image density on an electrostatic latent image carrier with high sensitivity and low cost. The degraded toner is processed based on the detected information, so that the waste toner can be reduced and a good image can be obtained. An image density of an image that is transferred with a predetermined reference electric field is detected in a first detecting step. An image density of an image that is transferred with an electric field that is smaller or greater than the reference electric field is detected in a second detecting step. A processing step of processing the degraded toner is performed on the basis of the image density detected by each of the detecting steps.

摘要： An image forming apparatus includes an image carrier for carrying a toner image and a transfer device. In the transfer device, a voltage applier applies a predetermined voltage to a transfer electric field generator. A potential measurement device measures a surface potential of the transfer electric field generator when a predetermined time period elapses after the voltage applier applies the predetermined voltage to the transfer electric field generator. A controller determines a transfer bias to be applied by at least one transfer member to the transfer electric field generator based on the measured surface potential of the transfer electric field generator. The at least one transfer member applies the transfer bias to the transfer electric field generator to generate a transfer electric field. The toner image is transferred from the image carrier onto a toner image receiver by the transfer electric field generated by the transfer electric field generator.
