TONER - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18300239 Titled 'TONER'
Simplified Explanation
This abstract describes a toner that has excellent low-temperature fixability and does not cause any development stripe. The toner contains a binder resin made of a crystalline resin. The toner's relative permittivity, which is a measure of its electrical properties, is measured under specific temperature and humidity conditions. The difference between the relative permittivity at a low frequency (0.01 Hz) and a high frequency (383 kHz) must fall within a specific range (0.21 to 0.48) for the toner to have the desired properties.
Original Abstract Submitted
A toner having both of excellent low-temperature fixability and such high durable developability as to be free from causing any development stripe. The toner is a toner including a toner particle containing a crystalline resin as a binder resin. When a relative permittivity obtained at a time of impedance measurement of the toner under an environment at a temperature of 25° C. and a relative humidity of 50% is represented by εr, a difference Δεr between a relative permittivity εr(0.01 Hz) at a frequency of 0.01 Hz and a relative permittivity εr(383 kHz) at a frequency of 383 kHz satisfies a relationship of 0.21≤{εr(0.01 Hz)−εr(383 kHz)}≤0.48.
