<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing the generation of troubles in image development even when a fibrous foreign substance is collected together with toner. <P>SOLUTION: An image forming apparatus collects toner left on a photoreceptor drum with a cleaner after transferring to a record sheet, and reuses the collected toner by returning it to developing equipment. The developing equipment is provided with an agitation screw 232 having a spiral blade 212, and a foreign substance collection part 214 is disposed on an outer periphery 221 of the spiral blade 212. The foreign substance collection part 214 is formed by a plurality of projections with hook shape on the ends thereof, having a gap therebetween, and collects pieces of fibers conveyed with the toner by tangling them on the ends of the projections. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
