摘要： PURPOSE:To obtain a toner with an excellent ambient stability by polymerizing a polymeric vinyl monomer to compose a binder resin and a monomer mixture including a colorant in a mixture dispersion medium made by mixing a specific amount of water and methanol. CONSTITUTION:A polymeric vinyl monomer to compose a binder resin and a monomer mixture including at least a colorant are polymerized in a mixture dispersion medium in which a hard water-soluble inorganic substance powder is used as a dispersant, and 20 to 80wt.% of water and 80 to 20wt.% of methanol are mixed. As a result, a minute particle toner with uniform particle diameter of the mean particle diameter 10mum or smaller suitable for forming a high resolution image can be manufactured economically. Furthermore, the particle diameter can be controlled by only changing the mixing ratio of the water and the methanol, and no special dispersant is necessary to use. Consequently, the ambient stability of the toner obtained in such a way is excellent.

摘要： PURPOSE:To produce toner particles having a sharp particle size distribution as well as satisfactory electrostatic chargeability by dispersing a colorant in a polymerizable monomer in the presence of a copolymer contg. specified sulfonic acid groups and carrying out suspension polymn. in a suspending medium. CONSTITUTION:A colorant is dispersed in a polymerizable monomer in the presence of a copolymer contg. sulfonic acid groups represented by formula I (where each of R1-R5 is H or methyl and the weight ratio of m:n is 98:2-80:20) and suspension polymn. is carried out in a suspending medium contg. an inorg. dispersant. A uniform toner having superior electrostatic chargeability, a sharp particle size distribution and superior resistance to moisture absorption can easily be produced.

摘要： PURPOSE:To improve pressure fixability, etc. and to enable fixing under pressure by compounding a petroleum resin consisting of C5 aliphat. hydrocarbon into a pressure-fixing component. CONSTITUTION:The petroleum resin consisting of C5 aliphat. hydrocarbon is obtd. by polymerizing the unsatd. hydrocarbon consisting of the aliphat. olefin and diolefin obtd. in the thermal decomposition stage for petroleum naphtha. A material which entangles easily with the fibers of usual paper by plastic deformation is used as the pressure-fixing component to be used in conjunction with said petroleum resin. The fixability equivalent to that of thermal fixing is thus obtd. with low pressure and generation of excessive gloss to transfer paper is obviated; moreover, the reduction in the weight and size of a fixing device is made possible. Blocking during preservation, offset to a pressing roller and filming to a photosensitive body and carrier are prevented.

摘要： PURPOSE:To obtain the toner which is excellent in fixability and non- offsettability by using a binder resin consisting of a specific vinyl polymer formed by reaction of a polymerizable vinyl monomer and a crosslinking agent. CONSTITUTION:A toluene-insoluble three-dimensional crosslinking structure is formed in the vinyl monomer formed by subjecting the polymerizable vinyl monomer constituting the binder resin and a mixture contg. the crosslinking agent and a coloring agent to suspension polymn. in such a manner that the crosslinking agent makes partial crosslinking reaction with the polymerizable vinyl monomer. The binder resin is so formed as to consist of the vinyl polymer of 3,000 to 12,000 number average mol. wt. contg. 3 to 30wt.% toluene-insoluble component. This binder resin does not, therefore, contain the intermediate mol. wt. component to exert adverse influence on the fixability and the non- offsettability and is constituted of only the low mol. wt. vinyl polymer formed partially with the three-dimensional crosslinking structure. The fixability and the non-offsettability are improved in this way.

摘要： PURPOSE:To obtain an encapsulated toner having stable particle diameter distribution by forming a hardened epoxy resin shell on the outside of each particle of a core substance contg. a pressure fixable binder resin, an epoxy resin, and a colorant and/or a magnetic powder. CONSTITUTION:A mixture of a core substrate contg. a pressure fixalbe binder, an epoxy resin, and colorant, and/or a magnetic powder is dispersed or dissolved into an org. solvent. The obtained liquid dispersion or soln. is dispersed into an aq. soln. contg. an epoxy resin hardening agent, and heated to form an outer shell on each particle of the core substance. Then, the org. solvent in the capsules is extracted with a lower alcohol to form an encapsulated toner. As said pressure fixable substance, higher fatty acids, their metal salts, higher fatty acid derivs., etc. are used, alone or in combination of >=2 of them. As said epoxy resin, bisphenol A type epoxy resins are used, and a compds. used for their hardening agent is a compd. for opening the ring of the epoxy group and linking thereto, such as amines, acid anhydride, or org. acid.
