When toner of the present invention finally is when making positively charged developer, charge control agent in the toner is a positive charge control agent, concrete example can comprise product, the organic quaternary ammonium salt of modifications such as nigrosine and fatty acid metal salts thereof, as tributyl hexadecyldimethyl benzyl ammonium 1-hydroxyl-4-naphtho-sulfonate and TBuA tetrafluoroborate etc.Positive charge control agent can use separately or two or more is mixed into enforcement usefulness.
According to above-mentioned proportioning, adhesive resin, colorant, release agent and charge control agent are weighed up weight, adopt traditional developer production technology can produce toner.--melting mixing--cooling--coarse crushing----classification--mix the back--screening that micro mist is broken that production craft step is: premixed.The particle that classification is come out is exactly a toner particle required in the developer of the present invention.To carry out premixed according to the high-speed mixer that adhesive resin, colorant, release agent and charge control agent that said ratio weighs up are put into Henschel production.After each composition fully mixes under high-speed stirred, with the screw mixing roll premixed potpourri is carried out melting mixing again, mixing temperature makes colorant and charge control agent be evenly dispersed in the adhesive resin under the situation of adhesive resin and release agent fusion between 110-180 ℃.Fully the potpourri behind the melting mixing can cool off fast by air-cooled or indirect water-cooling, and cooled potpourri carries out coarse crushing by beater grinder.Carry out the broken and classification of micro mist with the potpourri of injecting type jet mill grinding machine after again to coarse crushing.Control injecting type jet mill grinding machine, make in the volume distributed median of the particle after the classification diameter (MVD) value between 6.0-10.0 μ m, in the volume distributed median greater than the ratio of 20 μ m (V＞20) between 0-2%, diameter (MPD) value was between 4.0-9.0 μ m during number distributed, during number distributes greater than the ratio of 5 μ m (P＞5) between 60-100%, thereby obtain the toner particle described in the present invention.
External additive of the present invention is the small particle diameter hydrophobic silica of 5-20nm, is the combination of big particle diameter hydrophobic colloid silicon dioxide, metal organic compound micro mist and the polymkeric substance micro mist of 40-200nm through surface-treated mean grain size for the nascent mean grain size through surface-treated vapor phase method production.Using the nascent mean grain size of producing through the surface-treated vapor phase method small particle diameter hydrophobic silica as 5-20nm, is for the flowability that improves the toner particle and the speed and the stability of frictional electrification.The silicon dioxide of nascent mean grain size 5-20nm has very excellent flowability.Contain hydroxyl on the surface of general silica dioxide granule, this is a hydrophilic radical, is subjected to the influence of humidity in the air easily.Therefore, the silicon dioxide that is applied to the developer field is necessary its surface is handled, and makes silicon dioxide become hydrophobic silicon dioxide.Usually the silicon dioxide that is used for making positively charged developer being carried out the surface-treated treating agent has amino containing silane, hexamethyldisilazane and ring silazane etc., and the silicon dioxide that is used for making electronegative developer is carried out the surface-treated treating agent dimethyl silicone polymer, hexamethyldisilazane, dimethyldichlorosilane and hydrocarbyl si lanes etc.The big particle diameter silicon dioxide that the present invention uses is produced with colloid method, and this production method is fit to make the silicon dioxide of mean grain size more than 40nm, and the shape of the silica dioxide granule that obtains is spherical.Handle through surface hydrophobic again, can be well use as the external additive of developer.Big particle diameter silicon dioxide sticks to the surface of toner particle, mainly plays a part to isolate toner, prevents that toner cluster of grains coalescence from producing caking, improves heat-resisting quantity, anticaking capacity and the storage stability of developer.In addition, spherical big particle diameter silica bound sticks to the small particle diameter silicon dioxide of toner particle surface, and common flowability for the raising toner is made contributions.Like this, be higher than in environment temperature under 35 ℃ the situation, good powder flowbility has reduced because of fricative heat, effectively reduces the caking possibility occurrence of developer.Because the buffer action of the silicon dioxide of big particle diameter, significantly reduced that the silicon dioxide of small particle diameter imbeds the probability on toner surface in the middle of fricting movement, thereby make developer in the development under the hot conditions, keep stable, realize good, stable image output effect.
As the metal organic compound micro mist in the developer of the present invention can be zinc stearate micro mist, dolomol micro mist, calcium stearate micro mist etc., as polymkeric substance micro mist in the developer of the present invention can be polyvinylidene fluoride micro mist, ptfe micropowder, melamine-based micro mist etc.The surface that these micro mists stick to toner helps also preventing that developer is higher than in environment temperature to produce under 35 ℃ the situation reunites and caking, improve heat-resisting quantity, anticaking capacity and the storage stability of developer, and help improving the adaptability between developer and the organic photo conductor drum (OPC), make that the output of image is more stable.
According to above-mentioned proportioning, small particle diameter silicon dioxide, big particle diameter silicon dioxide, metallorganics micro mist and high molecular polymer micro mist are weighed up weight, the high-speed mixer of putting into Henschel production carries out high speed to be mixed fully, makes each external additive stick to the surface of toner equably.Again mixed potpourri is sieved on ultrasonic vibration sieve, dispel the thick particle that in the mixed process of back, produces, the developer that finally obtains the present invention and narrated.
