Claim Text:
1. A transfer device for an image forming apparatus having a plurality of transfer rollers configured to transfer an image to a transfer belt from a plurality of photoconductors, the transfer device comprising: a first slider member slidably moving to allow a first transfer roller among the plurality of transfer rollers to contact with a first photoconductor among the plurality of photoconductors or to be separated from the first photoconductor; a second slider member slidably moving to allow a second transfer roller among the plurality of transfer rollers to contact with a second photoconductor among the plurality of photoconductors or to be separated from the second photoconductor; a first cam member rotated by a cam rotating shaft to slidably move the first slider member; and a second cam member rotated by the cam rotating shaft to slidably move the second slider member, wherein the first cam member and the second cam member rotate such that a first point of time when the first transfer roller is separated from the first photoconductor is different from a second point of time when the second transfer roller is separated from the second photoconductor, wherein the second slider member simultaneously moving at least part of a time that the first slider member moves.
