    摘要： 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.

    摘要： The improvement is in the driving mechanism and positioning mechanism between an image bearing member and a main assembly of an image forming apparatus using the image bearing member. The image bearing member has a shaft receiving portion adjacent the center thereof to receive a positioning shaft of the main assembly when the image bearing member is mounted in said main assembly. By the receiving engagement, the image bearing member is correctly positioned with respect to the main assembly. The image bearing member is also provided with a driving force receiving portion where the image bearing member is engaged with a driving member of the main assembly so that the image bearing member can be driven from the main assembly. In such an arrangement, the shaft receiving portion and the driving force receiving portion are radially overlapped, at least in part, with each other as seen from a rotational axis of the image bearing member.
