Image forming apparatus

An image forming apparatus comprising:

• a paper delivery section for guiding paper delivered from a paper feed section, to a space between a photoreceptor and a transferring corona discharger, said paper being guided as turned over after having passed between a pair of arcuate reversing guides,
• a portion of said paper delivery section being formed as a unit which can be integrally pulled out from the body of said apparatus,
• the inner reversing guide out of said pair of reversing guides being attached to said unit at a predetermined position thereof so as to be movable between an original position in the vicinity of said photoreceptor and a retreat position which is lower than said original position and at which said inner reversing guide does not come into collision with said photoreceptor when said unit is pulled out;
• and
• guide lifting and lowering means adapted to retreat said inner reversing guide from said original position to said retreat position in association with a unit pulling operation, and adapted to return said inner reversing guide from said retreat position to said original position in association with a unit insertion operation.
