A toner for developing electrostatic latent images which comprises a colorant and two kinds of polyester is disclosed.The fFirst polyester is a nonlinear polyester that is composed of monomers including monomers of trivalence or higher valency and which satisfies the following conditions A1 and A2, the second polyester is a nonlinear polyester that is composed of monomers including monomers of trivalence or higher valency and which satisfies the following conditions B1 and B2, and the difference between the softening points of said first and second polyesters is at least 10.degree. C.condition A1: the monomers of trivalence or higher valency represent from 0.05 mol % to less than 15 mol % of all the monomers present;condition A2: the softening point is in the range of from 120.degree. C. to 160.degree. C.;condition B1: the monomers of trivalence or higher valency represent from 0.05 mol % to less than 15 mol % of all the monomers represent;condition B2: the softening point is in the range of from 80.degree. C. to less than 120.degree. C.

摘要:
A polyester for use as an electrophotographic toner composition is obtained by copolycondensation of (a) a diol component of polyoxyalkylene-bis(4-hydroxyphenyl)propane and (b) an acid component, improved by incorporating into the acid component a copolymer of styrene or a derivative thereof and a carboxylic vinyl monomer. A copolymer of an unsaturated aliphatic hydrocarbon and an unsaturated carboxylic acid and a polymer and copolymer of an unsaturated carboxylic acid may be used. The toner is improved in the prevention of off-set in the fixation step.
摘要:
An electrophotographic developer, such as a toner binder and a coating on a carrier, comprises a polyester having an acid value of 5 KOH mg/g or less and a hydroxyl value of 60 KOH mg/g or less, having a linear structure without crosslinking or a crosslinked structure provided by a monomer having three or more reactive groups. A toner having the polyester as a binder is effectively charged positively or negatively.

The present invention relates to a detergent composition which comprises (A) an amidoether derivative mixture (A) comprising an amidoether carboxylic acid or a salt thereof, an amidoether, and a glycerin derivative; and (B) a conditioning component, wherein the total amount of the amidoether carboxylic acid or a salt thereof and the amidoether is 50 wt % or more; the weight ratio of the amidoether carboxylic acid or a salt thereof to the amidoether is from 99:1 to 10:90; and the amount of the glycerin derivative is 5 wt % or less.
摘要:
A cover 10 is provided to cover the opening of a toner container 2. The cover 10 is attachable to, and detachable from, the toner container 2. A valve element 12 capable of closing the opening 11 formed in the cover 10 is pressed up to an opening position by a pressing-up portion 20 provided on a developing apparatus side. Shifting of the valve element 12 to the opening position makes it possible to supply the toner from the toner container 2 to the developing apparatus.
