  • Publication number: 20240118654
    Abstract: An image forming apparatus includes a body having an opening, a door on the body, a unit detachably attached to the body from the opening, a cover inside the door, a spring, and a lock. The door covers the opening at a first closed position. The unit is disposed at a mounting position inside the body. The cover is rotatable between a second closed position and an opening position in an opening direction. At the second closed position, the cover covers the unit at the mounting position. At the opening position, the cover forms an angle of 90 degrees or more with the body. The spring applies a force to the cover in the opening direction. The lock locks the cover at the second closed position. The cover displaced from the second closed position in the opening direction restricts a movement of the door to the first closed position.

  • Publication number: 20240053695
    Abstract: An image forming apparatus includes a photoconductor that bears an image and an intermediate transfer device that forms a primary transfer nip between the photoconductor and the intermediate transfer device. The intermediate transfer device primarily transfers the image from the photoconductor onto the intermediate transfer device at the primary transfer nip. A secondary transfer device forms a secondary transfer nip between the intermediate transfer device and the secondary transfer device. The secondary transfer device secondarily transfers the image from the intermediate transfer device onto a recording medium at the secondary transfer nip. At least one support shaft supports the intermediate transfer device. The at least one support shaft supports, on an identical axis, one lateral end and another lateral end of the secondary transfer device in a width direction of the recording medium.
