Abstract

PURPOSE:To remove a toner being stagnant on the detecting surface in the vicinity of a stepped part so that an exact detection can be executed, by providing plural slits for dividing the tip part in the width direction, on a cleaning elastic plate. CONSTITUTION:Plural slits 33 for driving a tip part 32 of a cleaning use elastic plate 31 in the width direction are provided, and plural cleaning chips 32a are formed. Accordingly, in a stepped part A, when the cleaning chips 32a positioned at both sides of the tip part 32 slidingly contacts the wall surface 1a of a carrying path 8 and brought to elastic deformation greatly, the cleaning chip 32a positioned in the center of the tip part 32 is brought to an elastic return independently, and can slidingly contact the detecting surface 28 of the stepped part A. In such a way, a toner being stagnant on the detecting surface 28 of the stepped part A can be removed, and an exact detection can be executed.
