Electrographic Process Apparatus TRIZ Cases
- Electrophotographic Photoreceptor Outermost Layer Durability
A photoreceptor outermost layer uses a cured film of charge transporting compound and polycarbonate resin to enhance electrical characteristics.
- Toner Cartridge Force Receiving Part Leakage Prevention
Segmented force receiving parts prevent developer leakage during transport by combining dynamic engagement with reliable sealing.
- Developing Device Magnetic Pole Arrangement Suppresses Fog
Optimized magnetic pole arrangement in a developing device suppresses vertical stripe-shaped fog by controlling developer movement.
- Fixing Device Anomaly Detection via Auxiliary Heater Control
A fixing device detects auxiliary heater anomalies by isolating the third heat generation member and measuring temperature changes on the fixing member.
- Image Forming System Conveyance Path Orientation Control
Reversing units align original sides to the image forming unit, preventing placement errors from shared paths.
- Developer Cartridge Detection Gear and Sensor Mechanism
A detection gear with an abutment projection moves a lever to trigger an optical sensor, eliminating separate sensors to reduce device complexity.
- Single Fan Cooling for Toner Container and Fixing Device
Segmented air passages distribute airflow from one fan to cool toner containers, IH coils, and sheets without adding device complexity.
- Intermediate Transfer Belt Stopping Control for Toner Adherence Prevention
A controller estimates temperature distribution along an intermediate transfer belt to determine a safe stopping position before the cleaning blade.
- Fixing Device Heat Leveling Roller Cleaning Mechanism
A fixing device integrates a brush rotating body with a heat leveling rotating body to clean the roller surface during operation.
