Developing Tank Filling Portion Position for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing developing devices face challenges in efficiently filling and transporting developing tanks filled with developers, as the filling portion on one side of the tank can lead to leakage during transportation due to shaking.
Innovation Solution
The developing device is designed with a filling portion on the opposite side of the developer carrier in the width direction, preventing developer leakage during transport by ensuring the developer does not reach the carrier, and allowing for easier filling and discharge operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filling portion is provided on one side in the longitudinal direction of the developing tank, then the operation of filling the developing tank with the developer is facilitated, but the developer easily reaches the developer carrier exposed from the developing tank and leaks out during transportation
Solution Approach 1:
The filling portion is moved from the longitudinal direction to the width direction of the developing tank, changing the spatial dimension of the filling operation. This dimensional shift allows the filling opening to be positioned on the side opposite to the developer carrier, facilitating easy filling while preventing developer from reaching the carrier during transportation.
2Ease of manufacture
If the filling portion is provided on one side in the longitudinal direction of the developing tank, then the filling operation is simplified, but the developer leaks out from the developing tank due to shaking during transportation
Solution Approach 1:
The developing tank is designed with asymmetric feature arrangement where the filling portion is positioned on one side in the width direction while the developer carrier is positioned on the opposite side. This asymmetric layout prevents developer from reaching the carrier during transportation while maintaining ease of filling operation.

AI summary
A developing device includes: a developing tank that is long in shape and that stores a developer; and a developer carrier that carries the developer stored in the developing tank. The developing tank includes a filling portion through which the developing tank is filled with the developer, the developer carrier is provided on one side in a width direction that is orthogonal to both a longitudinal direction of the developing tank and a vertical direction of the developing tank, and the filling portion is provided on the other side of the developing tank in the width direction, the other side is apart from the developer carrier.
