Abstract
The disclosure relates to a developing apparatus having a developing sleeve for making a latent image visible and a bucket roller for supplying developer to the developing sleeve including a plurality of buckets provided on the circumferential surface of the bucket roller at a predetermined spacing and base portions for supporting the buckets respectively. Each of the buckets are loosely provided at the base portions respectively so as to pivot with respect to the base portions. This construction effectively prevents the aggregation and accumulation of developer at the bucket portion, as well as gives sufficient flowability to the developer.
