发明名称 IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM
摘要 PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of performing fine transfer having no image defect even when transfer to rough paper having large surface ruggedness is performed, the width of a recording medium is narrower than the width of a photoreceptor, or transfer to the second surface of paper on which wrinkles are generated due to heat during the fixing of a toner image on the first surface is performed as to an image forming apparatus for electrostatically transferring a toner image formed on a photoreceptor to a recording medium. SOLUTION: A rotary member (5) to be rotated in accordance with the traveling of the recording medium (7) and a pressing mechanism (12b) for pressing the rotary member (5) to the photoreceptor (1) through the recording medium (7) are arranged in the vicinity of the entrance of a transfer part arranged between the photoreceptor (1) and a transfer means (3), and the surface of the rotary member (5) is charged with the same polarity as the charge of a toner image (9a) formed on the photoreceptor (1) or has the potential of the same polarity.
