Claim:
An image forming apparatus comprising: a body frame; a transport unit that transports a recording medium along a transport path in the body frame; an image carrier on which a toner image is formed, the image carrier carrying the toner image and transporting the toner image to a transfer position through which the recording medium is to pass; a transfer device that faces the image carrier at the transfer position, the transfer device nipping a recording medium passing through the transfer position together with the image carrier to transfer the toner image formed on the image carrier to the recording medium; a fixing device that is disposed on a side that is further downstream than the transfer position in a direction in which the recording medium is transported, the fixing device fixing the toner image onto the recording medium to which the toner image has been transferred at the transfer position; a guide member assembly including a guide member and a positioned portion, the guide member being positioned between the transfer device and the fixing device, the guide member guiding the recording medium to which the toner image has been transferred by the transfer device to the fixing device, the positioned portion being positioned at a position that is outside of a region through which the recording medium is to pass; a door that includes a base plate and supports the guide member assembly on an inner side of the base plate, the door opening and closing with respect to the body frame by rotating around a center line of rotation thereof that extends substantially in a width direction that crosses a direction in which the recording medium passes; and a positioning member that is supported by the body frame and that positions the guide member by being pressed by the positioned portion, wherein the door further includes a support shaft and an urging member, the support shaft being fixed to the base plate and extending substantially parallel to the center line of rotation with a gap between the support shaft and the inner side of the base plate, the urging member urging the guide member assembly in such a direction that the guide member assembly is separated from the base plate, wherein the guide member assembly includes a support member supporting the guide member and having a side wall that extends in such a direction as to intersect a line drawn in the width direction and that has a hole through which the support shaft is inserted with some play being present, and the guide member assembly is supported by the door with some play being present between the guide member assembly and the base plate and is urged by the urging member, and wherein the hole is a long hole having a major axis extending in an opening direction of the door away from the center line of rotation of the door.
