[Low-temperature fusing toner in pulverization]
Printers and copiers consume approximately 70% of their total energy in the process of fusing paper and toner.
Energy saving is essential for environmental conservation and eliminating impacts on the global environment, and hardware manufacturers are developing and promoting methods for lowering fusing temperatures.
Toner that can be melted and fused at low temperatures is also necessary from an operational/functional standpoint. In polymerized toner, elements such as capsule-structured toner containing large amounts of wax that contributes to fusing, and core-shell structures using resins with different glass transition points, have become mainstream, with each company emphasizing low-temperature fusing.
However, to secure toner through a pulverization system that excels in offset resistance while maintaining low-temperature fusing properties, it is essential to have attributes such as a high proportion of low molecular weight resins and large amounts of wax, and this requires technology that is extremely difficult in terms of the pulverization process.
With conventionally designed toner, the offset range is insufficient, and fusing defects can be easily anticipated due to factors such as environment, paper, and printing methods. Our company, however, has introduced new toner designs as a means to counter these problems, with the aim of achieving practical toner that has a wide fusing range and superior gloss properties, etc.
Patent No. 7141732 “Electrostatic Charge Image Developing Toner and Toner Cartridge”
[Toner with high charge stability]
Since toner is transferred using static electricity, the amount of static electricity (referred to below as triboelectric charge) becomes an extremely important factor.
The triboelectric charge can be controlled by resin and external additives, but it is possible to maintain high and stable triboelectric charge mainly with substances called charge control agents (CCA).
However, in recent years there has been a trend toward CCA-free products due to environmental considerations, and as an environmentally conscious approach, our company has achieved the provision of toner with high charge stability by adding substances with special charge-inducing properties to maintain specified triboelectric charge without adding CCA.
About toner cartridges
About recycling toner cartridges
We receive used laser printer cartridges from customers, disassemble them one by one, clean them, and repair damaged areas. We have established a recycling system where we fill these with new toner, reassemble them, and deliver them to customers.
Resource recycling
Resource recycling means reusing used products as resources. We have continually used Earth’s resources such as oil and coal. Thus, it is said that resources will be depleted within a few decades.
Furthermore, consumption of fossil energy such as oil and coal leads to carbon dioxide emissions, accelerating global warming.
We are participating in building a “sustainable recycling-based society” by recycling limited resources.
Recycling system
We support a “receive and remanufacture system” where we receive cartridges from customers and deliver recycled products. Furthermore, depending on the model, we also support a “pool system” where we deliver previously remanufactured cartridges.
Association of Japan Cartridge Re-manufactures
We are a regular member of the Association of Japan Cartridge Re-manufactures. Our company is an E&Q certified member, having cleared the “Environment and Quality” management standards established by the Association of Japan Cartridge Re-manufactures (AJCR).
