DEVELOPING DEVICE, PACKING MATERIAL FOR THE SAME, AND PACKAGE OF DEVELOPING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a developing device in which leaking of a developer is prevented when packed and transported without providing a sealing member separately, and to provide a packing material for the developing device and a package for the developing device.;SOLUTION: Three developing units 10 are arranged in a manner of a rotational symmetry and packed in a package 200. The magnetic poles of fixed magnets 11a in magnetic pole-arranged positions 66 inside developing sleeves 11b, which are exposed on opening sections 16 of the developing units 10, are the N poles. The magnetic poles of the fixed magnets 11a in magnetic pole-arranged positions 68 inside the developing sleeves 11b forming developing residual developer conveying paths 18 are the S poles. The N pole in the magnetic pole-arranged position 66 in one developing unit 10 and the S pole in the magnetic pole-arranged position 68 in another developing unit 10 are arranged to face each other so that the developing residual developer conveying path 18 is interposed therebetween.;COPYRIGHT: (C)2011,JPO&INPIT
