ABSTRACT:
A transfer device, which transfers an image onto a recording medium directly or indirectly and is included in an image forming apparatus, includes an endless belt member extended between a drive roller rotated and a driven roller and configured to receive the image from the image carrier part onto either a surface thereof or the recording medium carried on the surface thereof while moving according to rotations of the drive roller, and a rotation speed detector configured to detect a rotation speed of the driven roller. An image detector is provided either to the transfer device or to the image forming apparatus to detect the image formed on the endless belt member directly or the recording medium carried on the endless belt member, and disposed facing the driven roller in a circumferential direction of the endless belt member.
