PROBLEM TO BE SOLVED: To provide an image formation device capable of stably conveying an image formation medium in a reversely curled conveyance passage. SOLUTION: In a printer 12 of the image formation device 10, driving force is given to long photographic paper A pulled out of a magazine 16A by a pair of pulling-out rollers 18A by a pair of conveyance rollers 52 to let it pass through a reversely curled part WA having large conveyance resistance and wind it around a main driving roller 44. When it is wound around the main driving roller 44 by a predetermined angle, driving force is transmitted to the main driving roller 44 by an electromagnetic clutch, and transmission of driving force to the pair of conveyance rollers 52 is released. As a result, it is possible to avoid the occurrence of jamming of photographic paper between the main driving roller 44 and the pair of conveyance rollers 52 caused by difference in linear velocity of the rollers securely to convey the long photographic paper stably.
