Title:
DEVELOPING DEVICE
Document Type and Number:
Japanese Patent JPH1184835
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the occurrence of a deficient draw up of developer in the downstream of a 1st stirring shaft. SOLUTION: The developer is carried by a 2nd stirring shaft 3 from the center toward both ends in the axial direction, and the developer is carried by the 1st stirring shaft 2 from both ends toward the center in the axial direction. Thus, two developer circulation paths such as E1→F→E1 and E2→F2→E2 are formed, and the path length in the axial direction of the 1st stirring shaft is controlled to be half. Thus, the lowering of the developer level is reduced in the downstream of the 1st stirring shaft 2, then, the occurrence of the deficient draw up of the developer is prevented.
