  • Publication number: 20210271182
    Abstract: A high-voltage electrical circuit board is located in a first region that is a region at one side of photosensitive drums in a first direction and outside of the photosensitive drums in the first direction. A first motor drives a conveyance mechanism. A second motor is located in a second region and drives each photosensitive drum. A third motor is located in the second region and drives each developing roller to rotate and to drive a separation mechanism configured to individually move the developing rollers between a contact position and a separation position. A control board is located in the second region. The control board includes a controller configured to control a first applying circuit, the first motor, the second motor, and the third motor. The first motor, the second motor, the third motor, and the control board are located at different positions from one another in the second region.

  • Patent number: 9661167
    Abstract: A communication controller controls non-contact communication with an external device via an antenna while at least one of first and second power is supplied. A first circuit electrically connects a first power supply to a communication node. A second circuit electrically connects a second power supply to the communication node. The first circuit includes a first electrical component configured to prevent second power from being supplied to a particular target electrically connected to the first power supply while the second power is supplied to the communication node. The communication controller communicates with the communication node in a certain data communication method while the second power is supplied to the communication node. In response to reception of electric power from the external device via the antenna, the second power supply supplies the second power to the communication controller, and supplies the second power to the communication node through the second circuit.
