摘要： An output of a DC high voltage source is supplied as a bias to a heat fixing apparatus. An output of the DC high voltage source is divided by resistors, and a divided output is supplied as a DC bias to a charging apparatus. A feedback circuit generates a feedback signal corresponding to a difference between the divided output and a reference voltage, for supply to the DC high voltage source thereby controlling the divided output voltage at a desired value. Such structure allows a supply of a bias voltage to the heat fixing apparatus higher than the bias voltage to the charging apparatus, thereby eliminating defects in the fixing apparatus such as a fixation tailing or an offset phenomenon. Also the charging apparatus can be given an exactly controlled bias voltage, thereby avoiding a halftone density unevenness resulting from an uneven charging.

摘要： A reversely-rotatable roller conveys a sheet having an image formed on its one side at a sheet conveying velocity faster than that of a conveying roller by normal rotation and then, the reversely-rotatable roller conveys the sheet to a re-conveying path by reverse rotation. The sheet conveying velocity of the reversely-rotatable roller when the reversely-rotatable roller reversely rotates is made slower than the sheet conveying velocity when the reversely-rotatable roller normally rotates so that the sheet conveying velocity of the re-conveying roller is substantially equal to or slower than the sheet conveying velocity of the conveying roller.
