1. An image forming apparatus for forming an image on a recording material, said image forming apparatus comprising:
a first casing including a transfer unit constituted to transfer a toner image formed on an image bearing member to the recording material and a first discharging port constituted to discharge the recording material, on which the toner image is formed by said transfer unit, from said first casing;
a second casing including a first receiving port constituted to receive the recording material on which the toner image is formed by said transfer unit and a fixing unit constituted to fix the toner image onto the recording material, a height from an installing surface on which said image forming apparatus is installed to said first receiving port in a vertical direction being different from a height from said installing surface to said first discharging port in the vertical direction; and
a third casing provided between said first casing and said second casing, and including a second receiving port constituted to receive the recording material discharged from said first discharging port, a second discharging port constituted to discharge the recording material from said third casing and to deliver the recording material received from said second receiving port to said first receiving port, and an intermediary feeding member provided obliquely in the vertical direction from said second receiving port to said second discharging port,
wherein said second casing includes a first reverse feeding path constituted to reverse the recording material and feed the reversed recording material toward said first casing, and a first reverse discharging port constituted to discharge the recording material fed through said first reverse feeding path from said second casing,
wherein said first casing includes a first reverse receiving port constituted to receive the recording material reversed by said second casing, and a second reverse feeding path constituted to feed the recording material received from said first reverse receiving port toward said transfer unit, and
wherein said third casing includes a second reverse receiving port constituted to receive the recording material discharged from said first reverse discharging port, a second reverse discharging port constituted to deliver the recording material received from said second reverse receiving port to said first reverse receiving port, and a third reverse feeding path constituted to feed the recording material from said second reverse receiving port to said second reverse discharging port.
