Controlled 5–8 μm toner size and particle circularity help limit charge leakage and adhesion during thick-paper transfer in hot, humid conditions.

Silicon-rich aluminum rollers form surface anchoring features that limit belt slip and preserve toner fixing in low-temperature operation.

Controlled toner size and circularity distributions reduce aggregation and non-electrostatic adhesion for solid-image transfer in humid conditions.

This toner composition balances titanium oxide and silica adhesion to limit image fog and white streaks during toner reuse.

Small toner particles can adhere to fixing members in low-density images; a coated core with low-melting release agent helps prevent defects.

Controlled crystalline polyester and resin-particle surface ratios balance low-temperature fixing, heat-resistant storage, and cleanability.

A controlled silica adhesion ratio limits migration from white toner to colored toner, reducing charge leakage and transferred dusts.

An inclined discharge surface and controlled toner charge help limit aggregation, reduce pack residue, and minimize fogging during image formation.

Quinacridone pigments can aggregate and weaken tinting strength or paper fixability; a formula (1) compound improves dispersion during fixing.

A surface-enriched polyester resin layer helps toner soften at 150°C or less while improving paper adhesion, reducing scattering, and preserving image density.

An ester-bond binder resin and surface additive help stabilize toner charging while suppressing streaks and black spots in long-life printing.
