ABSTRACT:
An image forming apparatus having an intermediate guide device which is disposed at an intermediate portion between a transfer section and a fixing section for the purpose of guiding a transfer medium while imparting breadthwise tension thereto. This intermediate guide device prevents any wrinkle occurring in the transfer medium near the fixing section from being moved toward the transfer section. In addition, the toner on the transfer medium is prevented from being transferred onto upper-surface rollers of the guide device when the electric charge of the toner leaks to the rollers.
