Abstract
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.

An image formation apparatus comprising:
- 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,
- wherein the controller is configured to control the drive of the image carrier on the basis of a medium-detection result by the medium detector, and
- wherein the controller does not start driving the image carrier until the medium reaches at a predetermined position within a zone that allows transfer of the developer image to the medium to be performed at the image transfer position in time.
An image formation apparatus, comprising
- 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,
- wherein the controller is configured to control the drive of the image carrier on the basis of a medium-detection result by the medium detector, and
- wherein, until the medium reaches a predetermined position within a zone that allows transfer of the developer image to the medium at the image transfer position in time, the controller drives the image carrier at a lower speed than after the medium reaches the predetermined position.
An image formation apparatus, comprising:
- 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,
- wherein the controller is configured to control the drive of the image carrier on the basis of a medium-detection result by the medium detector, and
- wherein the controller starts driving the image carrier at a predetermined time after the medium detector detects the medium being feed along the medium conveyance path.
An image formation apparatus, comprising:
- 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,
- wherein the controller is configured to control the drive of the image carrier on the basis of a medium-detection result by the medium detector, and
- wherein, at a predetermined time after the medium detector detects the medium being conveyed toward the image transfer position along the medium conveyance path, the controller changes a driving speed of the image carrier to a faster speed than beforehand.
