Abstract: Provided is a fixing member including a base layer, and a surface layer on an outer surface of the base layer directly or with a primer layer interposed between the base layer and the surface layer, in which the surface layer is constituted by a single layer, the surface layer contains a fluororesin, and fluorine oil having a perfluoropolyether structure, and as for a measurement sample taken from the surface layer, when subjecting to predetermined treatments (i) and (ii), masses of an adhered material adhered in a unit area of a detection surface of a QCM sensor and containing the fluorine oil are within specific ranges.
Abstract: There is described a method for producing a fuser member. The method includes obtaining a substrate and positioning a fluoroplastic sleeve around the substrate. The outer surface of the fluoroplastic sleeve is roughened to a surface roughness of between about 0.03 ?m Ra and about 3 ?m Ra. The outer surface is coated with a functional silicone oil.
Abstract: An image forming method including forming an electrostatic latent image on a photoreceptor; developing the latent image with a developer including a toner using a center-feed developing device to form a toner image; transferring the toner image onto a receiving material; and fixing the toner image using a fixing member coated with silicone oil. The toner includes at least a binder resin; a colorant; and a quaternary ammonium salt having a specific formula, wherein when the toner is dispersed in ethanol using ultrasonic waves, the dispersion has a turbidity of from 0.4 to 1.0 when the turbidity is determined using a haze meter. An image forming apparatus including a photoreceptor; a center-feed developing device using a developer including the toner; a transferring device; a fixing device using a fixing member coated with silicone oil; and a cleaner for the photoreceptor.
Abstract: The presently disclosed embodiments are directed to release fluids or agents that are useful in release coating in toner-based technologies. More particularly, the embodiments pertain to the addition of metal chelating agents to release fluids to prevent byproduct reactions from the fusing process that would otherwise decrease fuser member life and image quality.
Abstract: The toner having a significantly improved dispersibility of a colorant in toner particles is provided. The present invention provides a dry toner comprising: (i) a binder resin; (ii) a colorant; (iii) at least one of metallophthalocyanine and a metallophthalocyanine derivative having a central metal selected from the group consisting of Cr, Fe, Co, Ni, Zn, Mn, Mg, and Al; and (iv) a polymer containing 0.5 to 20% by mass of a base unit derived from a specific polymerizable monomer having an amide group.
