Abstract
An image forming apparatus has rotatable members for rotatably retaining respective ones of flanges mounted to opposite ends of a roll sheet, and placement stages on which the roll sheet is to be placed and on which respective ones of the rotatable members are mounted. Racks are mounted to respective ones of the placement stages for undergoing movement to move the placement stages relative one another to vary a distance between the placement stages. A pinion is arranged between the racks for undergoing rotation to move the racks, and a potentiometer whose resistance value varies in accordance with a distance between the placement stages undergoing movement with rotation of the pinion is provided. An A/D converter outputs a value based on a resistance value of the potentiometer. A calculation device calculates a width of the roll sheet based on the value output from the A/D converter. A memory stores the calculated width of the roll sheet.
