<p>PROBLEM TO BE SOLVED: To suppress first spaces between bearings 207a and 207b and magnets 202a and 202b from being filled in an early stage with developer having passed through a magnetic seal 204.SOLUTION: A bearing housing part 210 which houses the bearings 207a and 207b has developer storage parts 220 and 221 as second spaces. The developer storage parts 220 and 221 are provided radially outside the bearings 207a and 207b, and communicate with first spaces 222 and 223 formed between the magnets 202a and 202b and the bearings 207a and 207b and can receive developer in the first spaces 222 and 223. Consequently, developer having passed through the magnetic seal 204 can be received in the developer storage parts 220 and 221.</p> |
