Glitter Developer Image Formation for Stable Metallic Luster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image formation apparatuses face challenges in maintaining stable metallic luster when using glitter developers, particularly as the remaining amount of glitter developer decreases during printing.
Innovation Solution
The apparatus includes a controller that adjusts the ratio of glitter developer images formed per unit area based on the remaining amount of glitter developer, ensuring consistent metallic luster throughout the use of the developer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a glitter developer is used to form a developer image, then a metallic luster can be obtained, but the metallic luster becomes unstable when the remaining amount of glitter developer decreases
Solution Approach 1:
The patent applies dynamics by making the image formation conditions variable based on the remaining amount of glitter developer. The controller dynamically adjusts development parameters (such as development voltage, development time, or developer supply amount) according to the detected remaining amount, allowing the system to adapt to changing developer conditions and maintain stable metallic luster throughout the developer's lifecycle
Solution Approach 2:
The patent implements feedback control by detecting the remaining amount of glitter developer and using this information to control the image formation process. The detector monitors developer quantity, and the controller adjusts formation conditions based on this feedback, creating a closed-loop system that maintains consistent metallic luster despite varying developer amounts
2Quantity of substance
If the remaining amount of glitter developer decreases, then the cost is reduced, but the metallic luster quality deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying image formation parameters (such as development voltage, current, or duration) based on the remaining amount of glitter developer. When the remaining amount is low, the controller adjusts parameters to compensate for reduced developer quantity, ensuring that metallic luster quality is maintained throughout the entire developer lifecycle from full to depleted state

AI summary
An image formation apparatus may include: a first image formation unit including a storage part and configured to form a glitter developer image; and a controller. The controller may be configured to control the first image formation unit, (i) upon forming a glitter image on a medium based on predetermined print data when a remaining amount of a glitter developer in the storage part is a first remaining amount, to form the glitter developer image with a ratio of the glitter image per unit area being a first area ratio, and (ii) upon forming the glitter image on the medium based on the predetermined print data when the remaining amount is a second remaining amount less than the first remaining amount, to form the glitter developer image with the ratio of the glitter image per unit area being a second area ratio greater than the first area ratio.
