Abstract
A drive transmission device includes a drive-side rotatable body, a plurality of magnetic conducting portions and a driven-side rotatable body. The drive-side rotatable body includes a plurality of magnetic poles arranged in a rotational direction. The magnetic conducting portions are magnetizable by the magnetic poles of the drive-side rotatable body. The driven-side rotatable body has a plurality of magnetic poles configured to be rotated in response to rotation of the magnetic poles of the drive-side rotatable body through the magnetic conducting portions. The drive transmission device is configured to be operated as a magnetic speed changer that changes a speed of rotation between the drive-side rotatable body and the driven-side rotatable body by differently setting the number of the magnetic poles of the drive-side rotatable body, the number of the magnetic conducting portions and the number of the magnetic poles of the driven-side rotatable body from each other.
