IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To solve problems of not increasing in paper feeding efficiency from an added recording paper housing part and reducing in image forming efficiency since there is a reversing carrying part for forming double-sided images when adding the recording paper housing part as an optional unit to an image forming device having a double-sided image forming function. SOLUTION: A reversing carrying passage is arranged in an added recording paper housing part to avoid the interference of a paper feeding carrying passage and the reversing carrying passage to avoid reducion in image forming efficiency when adding the recording paper housing part.
