Problems solved by technology

[0005] Furthermore, when the low-temperature fixable toner is put into the image forming apparatus and stored over time, due to environmental conditions, the toner particles or between the toner and the toner container are bound together, so there is a Problems with Unstable Toner Supply Amount Discharged from the Toner Container Discharge Port

preparation example Construction

[0035] There is no particular limitation on the production method of the toner of the present invention. In addition, conventionally known resins or colorants can also be used as the binder resin or colorant for toner.

[0036] The shape distribution of the toner particles suitable for the present invention preferably uses a shape distribution having a ratio of the major axis to the minor axis described below. In this way, good cleanability and transferability, excellent halftone (Ha-ft-n) images can be obtained, and stable high-quality images can be obtained.

[0037] (preferable toner particle shape)

[0038] Preferable toner particle shapes used in the present invention are, for example, defined as follows.

[0039] exist Figure 7 shows toner particles having the following shape: 1) At least one projected surface profile of each toner particle is sandwiched by two parallel lines in a contacting manner at points A1 and A2 The closed curve of the toner particle is the ma...

Embodiment

[0168] Hereinafter, the embodiments of the present invention will be specifically described by way of examples, but the present invention is not limited thereto.

[0169] 1. Toner Preparation

[0170] The toner is manufactured as follows.

[0171] (1) Production of colored particles 1

[0172] (Manufacture of resin microparticles A1)

[0173] In the reaction container that stirrer, temperature sensor, cooling pipe, nitrogen introduction device are installed, add 8 mass parts sodium lauryl sulfate and 3000 mass parts ion-exchanged water, stir with the stirring speed of 230rpm under nitrogen flow , allowing the internal temperature to rise to 80°C. After completion of the temperature rise, a polymerization initiator solution obtained by dissolving 10 parts by mass of potassium persulfate in 200 parts by mass of ion-exchanged water was added, and the temperature was adjusted to 80°C.

[0174] Next, a polymerizable monomer mixed solution containing the following compound was d...

Abstract

The invention provides a toner bottle for developing electrostatic latent images, which is filled with the toners below in a cylindrical toner container, the cylindrical toner container includes a rotary shaft capable of being engaged with an image forming device, and also includes an exhaust hole at one end thereof, the toner at least comprises a resin, a colorant and an external additive, conveyance index of the toner is 2.0 to 10.0 mg / sec, and X-ray intensity ratio of titanium to silicon (Ti / Si) determined via X-ray fluorescence spectrometry is 1.0 to 3.0, wherein the toner container has a plurality of projecting toner transporting portions which are intermittently provided on an interior wall of the container, the toner transporting portions can be rotated along with the toner container and transport the toners to the direction of the exhaust hole.

Description

technical field [0001] The present invention relates to a toner bottle for developing an electrostatic latent image. Background technique [0002] Currently, in image forming apparatuses such as copiers, printers, and facsimiles using an electrostatic latent image development method, dry toner is often used for development. At this time, a toner bottle or a toner container for storing dry toner is attached to the image forming apparatus, and toner is supplied from the toner container to the developing device. [0003] Therefore, as a toner container, it is desired to prevent toner leakage during storage and transportation, to be easily attached and detached from an image forming apparatus, and to suppress toner leakage when replacing the toner container. Not only is it low cost, but it can also be recycled and reused after use, so it is actively being developed and researched (Patent Documents 1 and 2). [0004] On the other hand, especially in digital image formation, it ...
