Solution Overview
Problem
Conventional image forming apparatuses experience deviations between the intended and actual positions of toner images on continuous media, such as label rolls, leading to misalignment issues during the image formation process.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the carrying speed of the recording medium is accelerated to correct position alignment, then the position accuracy of toner images is improved, but the complexity of speed control increases
Solution Approach 1:
The system uses interval detection parts to detect the actual interval of transferred toner images and feeds this information back to the control part. The control part then adjusts the carrying speed of the recording medium based on this feedback to correct position alignment, creating a closed-loop control system that automatically maintains position accuracy without complex manual intervention
Solution Approach 2:
The invention replaces complex mechanical speed control mechanisms with an information-based control system. By using interval detection parts to measure positions and a control part to process this information, the system substitutes mechanical adjustment complexity with electronic sensing and computational control, simplifying the overall system architecture
2Manufacturing precision
If interval detection parts are added to detect toner image positions, then position deviation is reduced, but device complexity increases
Solution Approach 1:
The interval detection parts serve multiple functions: they detect the positions of toner images, calculate intervals between consecutive images, and provide feedback for speed control adjustments. This multi-functionality reduces the need for separate detection and control components, thereby minimizing the increase in device complexity while achieving precise position deviation correction
Solution Approach 2:
The system uses the existing movement of the recording medium and toner images through the apparatus to enable self-detection of position intervals. The interval detection parts leverage the natural flow of materials through the system to gather positioning information without requiring additional actuation or complex detection mechanisms

AI summary
An image forming apparatus that forms developer images on a continuous medium includes a control part that performs a developer image forming on an intermediate transfer body with an interval; a transfer part that transfers developer images to the continuous medium; an interval detection part that detects the interval of positions to which the developer images; and an interval information memory that stores interval information of the interval. Wherein, the control part obtains the interval information from the interval information memory when starting an operation of forming the developer image, and determines a timing of forming the developer images on the intermediate transfer body based on the interval information, and when the interval is detected by the interval detection part, the control part updates the interval information in the interval information memory based on the interval that is detected.
