摘要:
This invention relates to image formation toner, 2-component developer, image formation method and method for manufacturing image formation toner, for preventing clogging of the filter. Toner is used in which the ratio of the component measured by GPC to have a molecular weight between 500 to 1000 is 10 parts by weight or less with respect to 100 parts by weight of the entire toner. Since the case of clogging of the HEPA filter is the 500 to 1000 molecular weight component, clogging of the filter is prevented by reducing this component.
摘要:
The present invention provides a toner for developing an electrostatic latent image comprising a releasing agent containing a hydrocarbon, a binder resin, and a colorant, wherein, when an average carbon number of the hydrocarbon is designated as N, the hydrocarbon contains components having a carbon number in the range of (N−10) to (N+10) in an amount of 70% by mass or more in the entire hydrocarbon and has a weight-average molecular weight of 12,000 or more and 25,000 or less, a developer for developing an electrostatic latent image containing the toner for developing an electrostatic latent image, and an image-forming process using the toner for developing an electrostatic latent image.
