摘要： An image forming apparatus includes a body frame, a transport unit, an image carrier, a transfer device, a fixing device, a guide member assembly, a door, and a positioning member. The guide member assembly includes a guide member, a positioned portion, and a support member. The support member supports the guide member and has 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. 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. 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.
