Recording medium processing device and image forming apparatus

A recording medium processing device comprising:

• a pair of contacting members including a first contacting member and a second contacting member, the first contacting member and the second contacting member being configured to contact each other at a contact portion and to contact a recording medium passing through the contact portion, a contact position of the second contacting member on the first contacting member being configured to change in response to displacement of the second contacting member with respect to the first contacting member in a state of being held in a position for recording medium transportation;
• and
• a guide member mounted to the second contacting member, the guide member being configured to guide the recording medium having passed through the contact portion at which the first contacting member and the second contacting member contact each other,
• wherein
• the second contacting member includes a member configured to rotate around a rotational axis and,
• the guide member is mounted to a rotary shaft of the second contacting member
• further comprising a rotating member mounted to the rotary shaft of the second contacting member and configured to rotate around the rotary shaft, wherein
• the guide member is mounted to the rotating member, and mounted to the rotary shaft of the second contacting member via the rotating member.

An image forming apparatus comprising:

• an image carrier having a surface on which a toner image is formed;
• a transfer member that forms a transfer nip by coming into pressure contact with the image carrier and transfers the toner image formed on the image carrier to a recording medium;
• a mounting portion that extends in an axial direction of the image carrier;
• a guide member that is mounted to the mounting portion and guides a recording medium passing through the transfer nip, the guide member being configured to rotate about a rotary shaft of the transfer member;
• and
• a disk-shaped member that is mounted to the mounting portion, wherein
• the disk-shaped member contacts a portion of the image carrier on which no toner image is formed.
