<P>PROBLEM TO BE SOLVED: To provide a development apparatus capable of effectively restraining the irregular supply of toner by surely preventing the flocculation of developer. <P>SOLUTION: The development apparatus is equipped with a toner reservoir chamber 22 and a developer stirring chamber 23 installed adjacently to the chamber 22 through a partition wall 24, is provided with a connection aperture 26 through which the chamber 22 and the chamber 23 communicate with each other on the partition wall 24, and also a magnet roller 40 facing to the aperture 26 and feeding the developer to the chamber 23 in the chamber 22, and is constituted so that prescribed stirring processing is performed to the toner fed to the chamber 23 by the roller 40. It is provided with a guide plate 90 whose base end side is fixed on the inner wall surface of the aperture 26 and whose leading end side pierces through the aperture 26 and projects to the chamber 23 side at the edge part of the aperture 26 opposed to the circumferential surface of the roller 40, whereby the flocculated toner is prevented from being supplied to the chamber 23 side by the plate 90. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
