<p><P>PROBLEM TO BE SOLVED: To provide a development apparatus, in a case where two conveying members conveying developer in the longitudinal direction to form a circulation path are installed facing a developer carrier and a developer regulation member is disposed at the lower part of the developer carrier, eliminating a trouble such as abrasion of the surface of the developer carrier and an increase in a driving torque of the device even if there are variations in a dimensional accuracy and assembling accuracy of components, and suppressing such a case that the developer after a developing process separated from the developer carrier in a second conveying path is carried by the developer carrier again; and to provide a process cartridge and an image forming apparatus. <P>SOLUTION: This development apparatus includes an elastic member 13w which pushingly moves a partition member 13d by an elastic force applied towards a developer carrier 13a to bring a part of the tip end of the partition member 13d in contact with the developer carrier 13a, and the partition member 13d partitions a first conveying path by a first conveying member 13b1 from a second conveying path by a second conveying member 13b2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
