摘要:
A toner is provided that exhibits a high long-term image stability even during high-speed printing and that also exhibits an excellent environmental stability. The toner comprises a binder resin, a colorant, and a nonionic surfactant, wherein the nonionic surfactant has an oxyethylene group (EO) and an oxypropylene group (PO) and has a ratio of the number of moles of the oxypropylene group to the number of moles of the oxyethylene group (PO/EO) of at least 0.01 and not more than 5.00; and when A (μg/g) is defined as a nonionic surfactant content on the surface of the toner that can be extracted by methanol from 1 g of the toner and B (m2/g) is defined as a theoretical specific surface area determined from a toner particle diameter distribution obtained by a precision particle diameter distribution analyzer that operates based on an aperture electrical resistance method, a ratio A/B is at least 100 μg/m2 and not more than 9000 μg/m2.

摘要:
A toner which has i) toner base particles containing at least a binder resin and a colorant and ii) a fatty acid metal salt composition as an external additive. The fatty acid metal salt composition contains a nonionic surface-active agent and a fatty acid metal salt. This toner and an image forming process making use of the toner can keep the toner from adhering to a toner carrying member throughout running, promise a stable chargeability of the toner and can keep any deterioration of halftone image quality from being caused by excess charging of the toner and any image fog from being caused by insufficient charging of the toner.
摘要:
A non magnetic toner comprises toner particles each containing at least a binder resin, a colorant and a wax component. The toner further comprises an inorganic fine powder. A storage elastic modulus at 110° C. (G′110) of the non magnetic toner is in a range of 2.00×104 to 2.00×105 dN/m2. A storage elastic modulus at 150° C. (G′150) of the non magnetic toner is in a range of 3.00×103 to 2.00×104 dN/m2. The toner particles are obtained by dispersing a polymerizable monomer composition containing polymerizable monomers, the colorant, the wax component and a low-molecular weight polymer into an aqueous medium, granulating the dispersed polymerizable monomer composition, and polymerizing the polymerizable monomers in granulated particles. The low-molecular weight polymer has a weight average molecular weight (Mw) measured by means of gel permeation chromatography (GPC) in a range of 2000 to 5000.
摘要:
In the image forming apparatus, upon reception of a job containing a file to be printed, it is determined whether or not the job contains a template indicating that a plurality of files are to be merged. If it is determined that the job contains the template, then the job is stored in a storage section. Based on the template, it is analyzed whether or not all jobs containing files to be merged have been stored in the storage section. If it is determined that all the jobs have been stored in the storage section, then control is exerted based on the template so as to merge and print the files contained in all the jobs. Thus, a plurality of files can be automatically merged and printed, and therefore the workload on the user can be reduced.

The present invention provides an image data processing method of recording image data coded with the MPEG (Moving Picture Experts Group) technique to a recording medium. For transition of the bit occupancy in a VBV buffer to a target value, the initial value of a bit occupany in a VBV buffer is calculated on the basis of auxiliary data read from a recording medium, a comparison is made between the target and intial values of the bit occupany, and the number of bits for assignment to each GOP of to-be-coded image data correspondingly to the result of comparison.

In a process cartridge having a latent-image-bearing member and a developing device having a developer-holding part and a developing member, at a vertical section which bisects in the process cartridge the surface of the latent-image-bearing member with which surface the developing member is brought into pressure contact, a developer agitation and transport member has at least two rotary agitation and transport members having rotating shafts falling at right angles with the vertical section. Where, at the vertical section, the area of the developer-holding part is represented by S1 and the area of the part corresponding to the movable region of the rotary agitation and transport member is represented by S2, the ratio of S2 to S1, S2/S1, is from 0.8 to 0.99; and the ratio of a long side Sa to a short side Sb, Sa/Sb, of a circumparallelogram having a minimum area in respect to the area S1 in the vertical section is from 1.5 to 3.0. The non-magnetic one-component developer contains at least a binder resin and a colorant and has a fluidity index of from 50 to 90 and a floodability index of from 45 to 96.
