Abstract
An image formation apparatus includes: an image formation device to form a developer image based on image data; a transfer device to transfer the developer image onto a recording medium; a fixing unit including a rotary body and configured to fix the developer image by rotating the rotary body in a first direction to move the recording medium to a downstream side in the conveyance path to heat and press the recording medium, and a wrap-around detection device to detect when the recording medium with the developer image is wrapped around the rotary body. The wrap-around detection device detects that the recording medium is wrapped around the rotary body based on a detected temperature of the rotary body and based on a medium detection result of detecting the recording medium on the upstream and downstream sides of the rotary body in the medium conveyance path.
