PURPOSE: To obtain a titled member which is easy to attach and detach and obviates the formation of the transfer irregularity of images on paper by providing fitting parts which are free to attach and detach to and from the shielding end part of a destaticizing corotron and arm parts extending on a corona wire from the fitting part side up to the opposite shielding end edge thereto.

CONSTITUTION: A corotron 2 is constituted of a pair of a transfer corotron 3 and a destaticizing corotron 4 each formed of a corona wire 6 and a metallic shield 5. Projections 5a are provided in the end edge part of the shield 5 on the corotron 4 side. Guiding members 7 are formed of fitting parts 8 assuming hollow grooves provided with projections 8a at about the width at which corona discharging is not interfered and arm parts 10. Said members are mounted to the end edge part of the shield 5 of the corotron 4 by the parts 8, so that the respective projections 5a and 8a engage with each other. The length of the parts 10 is determined at such a length at which said parts extend slightly beyond the central shield 5.
