A smooth core-shell toner with internal shell cracks improves low-temperature fixing, heat-resistant storage, and anti-blocking behavior.

Balanced quaternary-ammonium styrene-acrylic toner chemistry improves higher-order color reproducibility while keeping charge stable in high-speed printing.

Matched loss tangent and ester wax in CMY toners reduce layer peeling and ultrafine particles during full-color image fixing.

A 30-70% hydrogenated petroleum resin with crystalline polyester improves toner dispersibility, low-temperature fixing, and storage stability.

Adding 20% or more weak acid during toner particle fusion shortens fusion time, improves circularity, and suppresses coarse powder.

A metal-ligand charge control complex on EA toner surfaces improves charging across humidity extremes while reducing reliance on titanium dioxide.

Selective pixel reduction in the lowermost toner layer limits scattering and unwanted white edges on transparent media.

Controlled crystalline polyester, wax, and silica coverage help toner fix at low temperature while resisting blooming and charge leakage.

Low-Total-Energy toner with silica and fluorinated hydrotalcite resists compaction and electrostatic agglomeration in flexible storage bags.

By tuning amorphous and crystalline polyester compatibility, this toner improves low-temperature fixing, heat resistance, and blooming control.

Uniform Benard convection cells and optimized filler shape stabilize fixing belt roughness, reducing torque-up and frictional abrasion.

Silica agglomerate toner and a matrix-domain charging roller re-form a stable blocking layer to limit contamination and image density defects.

Silane-treated resin particles with anionic surfactant improve toner transfer efficiency while maintaining charging stability and reducing drum adhesion.

Specified blade modulus and breaking energy, paired with metallic toner shape control, improve cleaning and suppress toner filming on image holders.

Controlled hydrocarbon and ester wax migration helps toner fix at low temperature while preventing output paper sticking in compact high-speed printers.

A polyester toner with acid value control and a curing agent forms stronger crosslinked images that resist peeling and deterioration on ceramics.

A dual-structure pigment dispersant improves pigment adsorption and steric hindrance, boosting toner tinting strength and dispersion stability.

Specific dye and pigment ratios in fluorescent green toner limit concentration quenching while preserving high lightness and chroma.

Specific silicon, nitrogen, and sulfur ratios in external additive particles help toner retain flowability and image density in low humidity.

Controlling toner molecular weight distribution enables low-temperature fixing while preventing tacking and suppressing excessive image gloss.

By tuning polar and dispersion surface energy in fixed toner images, liquid wetting and adhesion improve without increasing release agent content.

Controlled resin viscoelasticity keeps external additives on toner surfaces, reducing uneven charging and device contamination.

Silicon-rich aluminum photoreceptors and low-Tg toner improve low-temperature fixing while preserving transferability and image quality.

Larger pressure-responsive particles and a broad glass-transition range improve toner-layer pressure transfer and printed media adhesiveness.

Balancing carrier-to-toner and carrier-to-drum adhesion improves toner transfer efficiency while stabilizing drum rotation and image quality.
