摘要:
A toner suitable for developing electrostatic images is produced through a process comprising: dispersing a monomer composition comprising at least a polymerizable monomer and a colorant in an aqueous medium heated at a temperature higher than a polymerization temperature, thereby to form particles of the monomer composition; adjusting the aqueous medium to the polymerization temperature; and adding a substantially water-insoluble polymerization initiator to the aqueous medium containing the particles of the monomer composition dispersed therein and adjusted to the polymerization temperature, thereby to cause the polymerization of the polymerizable monomer. According to this process, a toner containing a large amount of a low-softening point compound and having good fixability at low pressure and/or low temperature can be produced while retaining good anti-blocking characteristic and fluidity.
摘要:
The present invention relates to a non-magnetic mono-component toner composition, which comprises a) a non-magnetic toner particle comprising a binding resin comprising a binder resin and a copolymer of a cyclic olefin and an acyclic olefin polymerized in the presence of a metallocene catalyst and a cocatalyst, a colorant, and a charge-control agent; b) fine powder of an organic compound containing fluorine that is added to the surface of the non-magnetic toner particle; and c) hydrophobic silica having a specific surface area of 100 to 240 m2/g. The toner composition of the present invention has superior transfer efficiency and charging properties and thus can obtain a stable image, does not show deteriorated image density, and does not generate background contamination of non-image areas and off-set due to deterioration of fixing properties, even if copying or printing is conducted therewith for a long time use.
