Air pressure fluidizes toner and moves it through a filter and single discharge port, enabling stable replenishment with fewer conveyance components.

Periodic heating plus rotor impact speeds toner annealing, coalesces subdomains, and improves crystallinity and storage stability.

A fluorine-controlled hydrotalcite additive helps core-shell toner balance low-temperature fixing, durability, and resistance to cold offsetting.

Balancing fluorescent and non-fluorescent pigments by specific gravity helps toner keep fluorescence, bending resistance, peelability, and reflectance.

A balanced fluorescent and non-fluorescent pigment mix helps green toner avoid quenching while improving brightness, chroma, and hue accuracy.

Opposite roller rotation and a controlled speed ratio suppress toner deterioration, ghosts, and development stripes in long-term printing.

Reverse-polarity electrostatic control returns migrated external additives to toner, maintaining charge quantity and reducing fogging over time.

Varying blade roughness upstream and downstream stabilizes toner coating and triboelectric charging, reducing stripe defects and stagnation.

Hydrophilic fluorescent pigment and halogenated pigment improve toner dispersibility, suppress color migration, and keep gloss uniform.
