摘要： An image forming apparatus includes an image forming part, a transfer member, a carrying part, a control part, a contact/separation part that performs a separation operation through which the transfer member and the developer carrier become relatively separated, and a contact operation through which the transfer member and the developer carrier become in contact each other at a contact timing. Before the control part finishes transferring a developer image to a recording medium at a secondary transfer position, the contract/separation timing control part sets a separation timing, and the contact/separation performs the separation operation.

摘要： An image formation apparatus includes an image carrier; a charge member; an exposure unit; a development member; a measurement unit that measures a stop time period when a rotation of the image carrier is being stopped, or a physical amount that varies as the stop time period increases; a setting unit that sets a polarity of an initial voltage to be applied to the development member, the polarity being determined based on the stop time period or the physical amount measured by the measurement unit; and a power source unit that applies the initial voltage with the polarity set by the setting unit to the development member, at rotation start time of the image carrier.

摘要： An image forming apparatus includes an image forming part that forms a developer image, transfers the developer image to an intermediate transfer belt at a first transfer position and the developer image on the intermediate transfer belt to a sheet at a second transfer position. The image forming apparatus includes a detection part located between the first transfer position and the second transfer position and configured to detect a concentration of the developer image; and a controller configured to start a transfer of a concentration detection pattern that is a developer image for concentration detection during a period from when the developer image for print is transferred to the intermediate transfer belt to when the developer image for print is transferred to the sheet, and then to control the detection part to read the concentration detection pattern.

摘要： A medium processing apparatus includes a processor that performs a process related to a medium. The medium processing apparatus includes a discharging section, an operation section, and an operation controller. The discharging section discharges the medium. The operation section is disposed downstream of the discharging section in a discharging direction and includes a touch sensor. The discharging direction is a direction in which the discharging section discharges the medium. The touch sensor detects an operation input. The operation controller limits, on the basis of size information, detection operation performed by the touch sensor. The size information indicates information related to a medium size of the medium.
