According to one embodiment, an image forming apparatus includes an image bearing member, a charging roller, an exposure unit, a developing device, a transfer roller, and a control unit. The charging roller charges the image bearing member. The exposure unit forms an electrostatic latent image on the surface of the image bearing member. The developing device develops the electrostatic latent image formed on the surface of the image bearing member into a toner image. The transfer roller transfers the toner image from the image bearing member. The control unit detects a resistance detection voltage of the transfer roller as a voltage for detecting that there is an abnormality in the image bearing member.

A server includes a transceiver and a controller. The transceiver is configured to facilitate communication with a plurality of image forming apparatuses. The controller is configured to receive adjustment information from each of the plurality of images forming apparatuses, determine an updated adjustment value to be used in each of the plurality of image forming apparatuses based on the adjustment information received from of each of the plurality of image forming apparatuses, and transmit adjustment update information including the updated adjustment value to each of the plurality of image forming apparatuses.

Image forming system and voltage adjustment method

According to one embodiment, an image forming apparatus includes a fixing roller, a heater, a heater controller, and a roller controller. The fixing roller conveys a sheet by rotation and fixes a recording material formed on the sheet to the sheet. The heater heats the fixing roller. The heater controller controls a temperature of the heater. The roller controller controls a rotation speed of the fixing roller. When the roller controller satisfies a predetermined condition indicating that a fixing part temperature indicating a temperature of the fixing roller is not suitable for operation, the roller controller increases a rotation speed to be higher than a rotation speed of a case in which the predetermined condition is not satisfied.

Certain embodiments provide a transfer apparatus, which including: an conductive intermediate transfer member; a transfer section configured to secondarily transfer a toner image onto an image receiving medium in a constant current system; a conveyance section configured to convey the image receiving medium; and a high voltage transformer configured to apply a bias to the transfer member, wherein the sum of the products of the volume resistivities [&#x3a9;&#xb7;cm] and the thicknesses [cm] of the intermediate transfer member and the transfer member is equal to or greater than 3.6&#xd7;10&#x3a9;&#xb7;cm, and the conveyance speed V[mm/s] of the image receiving medium={the output upper limit value A[V] of the absolute value of the voltage output from the transfer polarity side of the high voltage transformer}&#xd7;0.009.

Transfer apparatus and image forming apparatus

An embodiment provides an image forming apparatus that has a first operation mode and a second operation mode. The first operation mode forms an image on a sheet with toner. The second operation mode decolorizes the toner on the sheet on which the image is formed with a decolorable toner having a decoloring function. In the first operation mode, when the sheet passes through a transfer unit, a transfer bias having the same polarity as that of a charge of the toner is applied to the transfer member and a toner image formed on a surface of the transfer member is transferred to the sheet. In the second operation mode, when the sheet passes through the transfer unit, a cleaning bias having a reverse polarity to that of the transfer bias is applied to the transfer member.

Image forming apparatus

An image forming apparatus includes a first image forming unit configured to form a first image to be transferred to a sheet with a first toner that is decolorizable and has a first brightness, and a second image forming unit configured to form a second image to be transferred to the sheet with a second toner that has a second brightness that is greater than the first brightness. At least a part of the first image transferred to the sheet is formed above the second image transferred to the sheet.
