Abstract: An erasing device includes a line scanner on an upstream side in a recording medium conveying direction, includes a thermal head downstream in the recording medium conveying direction of the line scanner, and includes a platen in a position opposed to the thermal head as a heating device across a recording medium conveying path. The erasing device causes the heat generating elements of the thermal head in positions corresponding to color and density sensors in positions of an image detected by the line scanner to generate heat. The erasing device controls, according to detected colors or density, a quantity of heat to be generated.

Abstract: An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.
