Abstract
When it is judged that a sheet S is not an ordinary paper but a thick paper or an OHP film sheet, or that the arrival of the sheet S at a pair of timing rollers 48 is delayed due to a slip for example beyond an allowable period of time, a controller 70 judges that a condition for transferring or fixing an image on the sheet S is not met. As a result, a secondary transfer roller 34 and a cleaner 38 are retreated from an intermediate transfer belt 12, and in this state, the intermediate transfer belt 12 carrying a toner image I thereon is made idle at least about one revolution without transferring the image I.
