Conveyance device and image forming system

Abstract

A conveyance device includes: a conveyance route that conveys a recording material supplied from a recording material supplier to an image former; a multiple feeding detector that detects multiple feeding of the recording material supplied from the recording material supplier; a medium sensor that detects characteristic information corresponding to a characteristic of the recording material; and a branch route that branches off the conveyance route at a branch portion on the conveyance route and purges the recording material whose characteristic information has been detected by the medium sensor, without causing the recording material to pass through the image former. The recording material about which the multiple feeding has been detected by the multiple feeding detector is purged via the branch route.
