摘要： PROBLEM TO BE SOLVED: To provide both- and one-face modes and to make a recording material hardly generate a jam, regardless of the fact that the recording material can be passed through a fixing unit several times in the one-face mode. SOLUTION: A reversing/refixing submode for turning a recording material inside out after being passed through a fixing unit 400 once and then, passing the recording material through the fixing unit again at least once, during a one-face mode of forming an image only on one surface of the recording material S is selectably provided. The reversing/refixing submode is selected according to the kind of recording material S and the kind of image quality obtained after fixation. Reverse return paths 93 and 94 for the recording material in the both-face mode, are used in the reversing/refixing submode. The reverse return paths 93 and 94 are formed in such length that plural recording materials S can be housed.
