Electrography/Magnetography TRIZ Cases
- CRUM Chip Integrity Detection for Printer Consumable Communication
Accumulating integrity detection data in a CRUM chip prevents noise-induced errors and hacking during consumable unit communication.
- Matted Reflecting Face for Uniform Static Elimination
A matted reflecting face directs static eliminating light across a photosensitive drum surface to ensure uniform exposure.
- Electrophotographic Photosensitive Member Copolymer Composition
A photosensitive member surface layer uses a specific copolymer composition to increase film density and dissipate external stress as heat.
- Electrophotographic Photoreceptor Charge Transport Layer Composition
A charge transport layer uses a polyarylate resin with specific dicarboxylic acid and diol units alongside a high-concentration charge-transporting material.
- Process Cartridge Varying Thickness Resin Flow Stabilization
A process cartridge frame member uses a varying thickness portion to stabilize resin flow during molding and adhere a conductive sheet integrally.
- Intake Duct Uniform Cooling Image Forming Unit
Segmented air intakes along the enclosure wall feed an elongated duct that distributes cooling air uniformly across the photosensitive member shaft.
- Image Bearing Member Protective Agent Torque Ratio
Optimized drive torque ratios between the image bearing member and foam-based supply member remove toner while preventing abrasive wear.
- Electrophotographic Photoreceptor Thickness Ratios Ghost Prevention
Specific thickness ratios between the charge transport and undercoat layers minimize ghosts and color spots in electrophotographic photoreceptors.
- Charging Member Elastic Layer Wear Reduction
A charging member with a low-modulus elastic layer optimizes contact width and voltage distribution.
