Image formation apparatus

摘要

An image formation apparatus includes an image carrier on which a developer image is to be formed, an image transfer device configured to transfer the developer image formed on the image carrier to a medium at an image transfer position, a controller configured to control drive of the image carrier and the image transfer device, a first medium feeder configured to feed the medium to the image transfer position along a medium conveyance path extending from the first medium feeder to the image transfer position, and a medium detector provided between the first medium feeder and the image transfer position in the medium conveyance path. The controller is configured to control the drive of the image carrier on the basis of a medium-detection result by the medium detector.

1. An image formation apparatus comprising:
an image carrier on which a developer image is formed; an image transfer device configured to transfer the developer image formed on the image carrier to a medium; a controller configured to control drive of the image carrier and the image transfer device; a first medium feeder configured to feed the medium in the medium-conveyance direction to convey the medium to the image transfer device; a medium-size detector configured to detect a conveyance-direction dimension of the medium; and a leading-end detector provided at a first distance from the image transfer device in a downstream direction and configured to detect the leading end of the medium discharged from the image transfer device, wherein the controller is configured to stop driving the image carrier, when the medium is conveyed over a distance obtained by subtracting the first distance from the conveyance-direction dimension after the leading-end detector detects the leading end of the medium.
