Electrography/Magnetography TRIZ Cases

A particle filter varies thickness and pore density across a curved flow passage to maintain uniform collection efficiency.

A cleaning member uses electrostatically implanted fibers lying flat on a base fabric to contact and remove contaminants from photosensitive drums.

A movable lever carries an electrical contact that joins a main-body-side contact to detect cartridge presence.

Upper and lower flickers segment scraping action on the conveyance screw, eliminating dead spaces where solidified toner causes blockages.

An auger transports scraped toner from the first axial end toward the second end, preventing accumulation in the storing portion.

A polycarbonate copolymer terminates chains with aromatic or fluorine groups to improve solubility in organic solvents.

Relocating guide portions to the cleaning frame prevents incompatible cartridge insertion while reducing space between adjacent cartridges for downsizing.

A single-layer photosensitive member uses a binder resin with controlled molecular weight to achieve specific mechanical strain and scratch resistance.

A protecting agent-supplying device deposits fatty acid zinc salt and boron nitride onto an image bearing member to form a protective layer.

Surface roughing on a collection sheet member reduces stick-slip vibration noise without requiring expensive lubricative particles.

A cleaning blade holder uses a swaged claw to mechanically secure the blade portion without adhesives.

An undercoat layer with silicone oil and particles relieves internal stress in electrophotographic photosensitive members.

Charge transport layer with specific hole transport material and compound forms a complex to stabilize electrostatic properties against oxidizing gases.

A charge transport layer combines a specific polyester resin with a charge-transporting compound to enhance hole mobility.

An insertion portion fits into a receiving portion with a locking structure to prevent loosening from vibrations without requiring welding equipment.

Integrated coupling grooves on stay members enhance structural rigidity between frames, preventing sheet skewing during image conveyance.

A control section adjusts cleaning blade speed and voltage to manage lubricant concentration on the image bearing member.

A photosensitive member uses ferroelectric particles with conductive coatings to enhance dielectric relaxation and electrical conductivity.

A toner conveyance belt uses a guide member to prevent accumulation on the driven roller.
