  • Electromagnetic field control member
    Patent number: 11380456
    Abstract: An electromagnetic field control member includes an insulating member constituted of a cylindrical ceramic and having a plurality of through holes along an axial direction, a conductive member constituted of metal and closing the through holes so as to provide an opening that opens in an outer periphery of the insulating member, and a power supply terminal connected to the conductive member. The power supply terminal is located away from an inner wall of the insulating member forming the through holes, and has a first end and a second end in the axial direction, and at least one of the first end and the second end is located farther away from the inner wall than a central portion of the power supply terminal.

  • Adjusting mechanism of image forming apparatus
    Patent number: 11188017
    Abstract: An image forming apparatus includes a first unit, a second unit, a first adjusting member, and a second adjusting member. The first unit includes an endless first belt member and a first rotating member that rotates while supporting the first belt member. The second unit includes a rotatable second rotating member that opposes the first rotating member with the first belt member interposed therebetween. The first adjusting member is disposed on either one of the first unit and the second unit to adjust a load between the first rotating member and the second rotating member. The second adjusting member is disposed on the other one of the first unit and the second unit to adjust parallelism between the first rotating member and the second rotating member.
