Abstract

PURPOSE:To clean the space between a magnetic blade and a sleeve easily by providing the blade movably. CONSTITUTION:¦A magnetic blade 3 is provided opposite to a developing sleeve 1. The blade 3 sandwiched between a support 4 and a support 5, and the supports 4 and 5 are connected by means of plural shafts 7. The blade 3 is formed with slots 6 in the positions opposing to the shafts 7, and is supported immovably laterally but movably vertically. In order to hold the blade in an up position when the blade is detached from the developing sleeve for the purpose of cleaning, a lever 8 is provided to the side part of the blade, and a projection 9 permitting hanging of the lever 8 is formed to the support 4. During developing, the magnetic blade is attracted toward the developing sleeve by a magnet 2, and the magnetic blade is positioned by the top edge of the slots 6 and the shafts 7.
