ABSTRACT:
An image forming apparatus has an image bearing member and a main body with an internal conveyance path for conveying a transfer material. An opening/closing member is attached to the main body and is displaceable between a closed position and an opened position where the conveyance path is exposed. A cover is set to cover a part of the image bearing member facing the conveyance path when the opening/closing member is open and is retracted from the conveyance path when the opening/closing member is closed. A moving mechanism slides the cover. Front and rear frames are held movably by the moving mechanism and are attached respectively to front and rear edges of the cover in a sliding direction. A tension applying mechanism acts on the frames to apply tension to the cover in the sliding direction during a sliding movement of the cover.
