Cleaning Device for Image Holding Unit with Movable Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in completely removing deposits from image holding units, particularly external additives that can lead to filming, which affects image quality and is difficult to manage with conventional cleaning tools.
Innovation Solution
A cleaning device with a movable cleaning tool and guiding unit that allows for precise contact and movement between non-contact and contact positions, ensuring effective removal of deposits from the image holding unit, including the use of a cleaning rod and guide mechanism for maintaining optimal contact pressure and reducing deposit fall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning tool is used to remove deposits from the image holding unit, then cleaning effectiveness is improved, but the risk of damaging the image holding unit increases
Solution Approach 1:
The cleaning tool is designed to be movable along the intersecting direction, allowing dynamic adjustment of contact pressure and cleaning intensity. The guiding unit enables the cleaning tool to move between non-contact and contact positions, providing controlled interaction with the image holding unit surface to remove deposits effectively while minimizing damage risk.
2Reliability
If the cleaning tool moves along the intersecting direction, then deposit removal capability is improved, but contact control precision becomes more difficult
Solution Approach 1:
The guiding unit acts as an intermediary mechanism between the cleaning tool and the image holding unit. It provides precise guidance and control for the cleaning tool's movement along the intersecting direction, ensuring accurate positioning and consistent contact pressure while enabling effective deposit removal.
3Device complexity
If conventional cleaning tools are used, then device simplicity is maintained, but ability to remove filming and external additives is insufficient
Solution Approach 1:
The cleaning tool is configured to move along an intersecting direction that is different from the conventional cleaning direction. This dimensional change in cleaning approach enables the tool to effectively remove filming and external additives that are difficult to remove with conventional cleaning tools, while the guiding unit maintains reasonable structural complexity.

AI summary
A cleaning device that cleans a surface of an image holding unit capable of holding an image formed using an image forming material includes: a cleaning tool that is movable along an intersecting direction intersecting with a moving direction of the image holding unit and cleans the surface of the image holding unit when placed in a contact position where the cleaning tool is in contact with the surface of the image holding unit; and a guiding unit that guides the cleaning tool so that the cleaning tool moves from a non-contact position where the cleaning tool is not in contact with the image holding unit to the contact position for cleaning the surface of the image holding unit, wherein when the image holding unit is moved, the cleaning tool placed in the contact position cleans the surface of the image holding unit.
