<p>A developing device (4) includes: a developer container (40) having first and second transport passage (40b)s, for containing developer; a developer carrier (20) for carrying, on its surface, developer inside the second transport passage (40b); a first stirring/transporting member (31) having a rotary shaft (31a) and a transport blade (31b) formed on its circumferential surface, for stirring/transporting developer inside the first transport passage (40a); a second stirring/transporting member (32) for stirring/transporting developer inside the second transport passage (40b) in a direction opposite to the first stirring/transporting member (31); a first developer passing portion (40d) for delivering developer from the first to the second transport passage (40b); and a second developer passing portion (40e) for delivering developer from the second to the first transport passage (40a). In a part of the first stirring/transporting member (31) facing the first developer passing portion (40d), a paddle portion (50) is formed which is devoid of the rotary shaft (31a) and which has a plurality of first ribs (51 a, 51b) parallel to the rotary shaft (31 a).</p> |
