摘要： An image forming apparatus includes an image bearer, an image forming device to form a toner image on the image bearer with toner, a power source to output a bias to transfer the toner image onto a recording medium, and control circuitry. The circuitry controls the power source to decrease a peak-to-peak voltage of the bias in response to increase in at least one of temperature and humidity, when a time-averaged voltage of the bias is on a transfer side of transferring the toner to the recording medium, from a median value of maximum and minimum voltages of the bias. The circuitry controls the power source to increase the peak-to-peak voltage of the bias in response to increase in at least one of temperature and humidity, when the time-averaged voltage of the bias is on a return side of returning the toner to the image bearer, from the median value.

摘要： An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developing unit that develops the electrostatic latent image using a toner; an intermediate transfer body onto which toner image is transferred; a secondary transfer member that comes in contact with a surface of the intermediate transfer body; a power supply that outputs a voltage for transferring the toner image on the intermediate transfer body onto a recording member; and a protective agent supply unit that applies a protective agent including zinc stearate and boron nitride onto a surface of the image carrier. The voltage is alternatively switched in a transfer direction and an opposite direction. The voltage in the transfer direction enables transfer of the toner image from the intermediate transfer body to the recording member, and the voltage in the opposite direction has polarity opposite to polarity of the voltage in the transfer direction.

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.

摘要： An image forming apparatus includes an image bearing member to bear a toner image on a surface thereof, a transfer device to transfer the toner image onto a recording medium, and a transfer bias power source to apply to the transfer device a superimposed transfer bias in which an alternating current (AC) component is superimposed on a direct current (DC) component in a superimposed transfer mode to transfer the toner image. The superimposed transfer bias has a waveform in which a first polarity in a direction of transferring the toner image onto the recording medium and a second polarity opposite the first polarity switch alternately. The superimposed transfer bias is output such that a standard value of each of the DC component and the AC component is multiplied by a respective correction ratio, and the correction ratio of the DC component is different from that of the AC component.

摘要： An image forming apparatus includes a transfer bias output device and an information receiving device. The transfer bias output device outputs a transfer bias including a superimposed bias composed of an AC bias superimposed on a DC bias to form a transfer electric field in a transfer nip between an image bearing member bearing a toner image and a nip forming member, to transfer the toner image onto a recording medium in the transfer nip. A controller operatively connected to the information receiving device and the transfer bias output device causes the transfer bias output device to change a target output of a peak-to-peak voltage of the AC bias based on information received by the information receiving device that affects transfer of the toner image and to reduce a target output of the DC bias as the target output value of the peak-to-peak voltage of the AC bias increases.

摘要： An image forming apparatus includes a power source to output a voltage having an alternating waveform to transfer a toner image from an image bearing member to a recording medium. A time-averaged value (Vave) of the voltage has a polarity in a transfer direction, in which the toner image is transferred from the image bearing member to the recording medium, and an absolute value of the time-averaged value is greater than a midpoint value (Voff) of the voltage intermediate between a maximum value and a minimum value of the voltage. As a roughness of the recording medium increases, a duty ratio (Duty) expressed by A/(A+B) is reduced, where A is an area of the waveform of the voltage in a return direction opposite the transfer direction relative to the midpoint value in one cycle and B is an area in the transfer direction relative to the midpoint value.
