There is provided a toner which is excellent in temporal stability and environmental stability of charges and which is capable of forming images that contains almost no background fog and has high density even in a long-term use and in use at a high-temperature and high-humid circumstance, and furthermore the toner which is not scattered inside an image forming apparatus and thus causes no contamination inside the apparatus, and there is further provided a method of manufacturing the above toner. An organic boron compound is contained as a charge control agent, a surface CCA concentration per specific surface area of toner falls in a range from 2.1×10−6 g/cm2 to 5.5×10−6 g/cm2, and a surface CCA concentration is 1.8×10−3 g/g or more.

A hair styling iron A is provided comprising: a body 1 which includes a grip portion 4, a plate portion 6 including a heater H and a plate 8, and a fulcrum portion 5; and a sandwiching member 2 which includes a lever portion 15 opposed to said grip portion 4, a plate portion 17 equipped with a heater H and a plate 18 and opposed to the plate portion 6 of the body 1, and a fulcrum portion 16 located between the lever portion 15 and the plate portion 17 and pivotally supported by the fulcrum portion 16 of the body 1. Between the rearward portions of the fulcrum portions of the body 1 and the sandwiching member 2 is interposed a spring 12 which biases the plate portions 6 and 17 normally in the direction away from each other. Each of the plate portions 6 and 17 is provided with ridges 14 along the perimeter, and has been subjected to a flocking treatment from its perimeter to the outer surface.

The present invention provides a reflection sheet that is used together with a prismatic light guide plate for the backlight of a liquid crystal display device, wherein the reflection sheet makes it possible to create a liquid crystal display device that has high brightness as well as few bright lines, bright spots, and brightness defects (moiré), that possesses improved resistance to damage on the prismatic light guide plate and reflection sheet, and that can preserve high brightness over a long period of time; and provides a backlight in which such reflection sheet is used. In the present invention a prism layer is formed on one surface of a reflection sheet, the vertex angle of the prisms is 145° or greater and 168° or less, and the distance between the vertices of the prisms on the reflection sheet is 50 μm or greater and 550 μm or less. The reflection sheet is arranged in such a way that the prism array direction of the reflection sheet makes an angle of 5° or greater and 20° or less with respect to the prism array direction of the prismatic light guide plate.

An object of the invention is to provide a black toner that can satisfy further the requirement for low energy, high-speed and high performance, a color toner that can be used in an image forming apparatus provided with an oil-less fixation device, and a color toner including the black toner and the color toner. For the black toner, a polyester resin having an acid value of 7 to 20 mgKOH/g is used as the binding resin, and a carboxylic acid-modified paraffin wax having an acid value of 4 to 30 mgKOH/g is used as the wax. For the color toner, polyester resin having an acid value of 7 to 20 mgKOH/g is used as the binding resin, and a carboxylic acid-modified paraffin wax having an acid value of 6 to 25 mgKOH/g is used as the wax.
摘要:
When a dial is operated to rotate forward to a DEF position with a knob 52 staying in a depressed state, a cam portion 12 operates a key operating portion 56 to move in an approaching direction in which the key operating portion 56 approaches a reset key 39, so as to operate the reset key 39 as a result of the key operating portion 56 moving in the approaching direction. Then, a push button 31 returns from a depressed position to a normal position, and interlocking with the push button 31, the knob 52 returns from the depressed state to a normal state. Due to this, since the driver only has to operate the dial 4 to rotate forward to the DEF position so that the knob 52 can be forced to return from the depressed state to the normal state, the operability is increased.

A positive electrode plate (11) and a negative electrode plate (12) are coiled around into a flat shape such that positive electrode layer faces (22a-22e) and negative electrode layer faces (23a-23f) are alternately layered upon one another with a separator interposed therebetween. Positional discrepancy detecting holes (41a, 41b, 42, 43, 44) are formed in the positive electrode layer faces (22a, 22b) and negative electrode layer face (23a) facing each other at the coiling start end, and in the positive electrode layer face (22e) and negative electrode layer face (23f) facing each other at the coiling finish end. The electrode plates are coiled into an electrode plate group, which is subjected to X-ray inspection for detecting positional displacement based on a discrepancy in the positions of the holes.

A toner is provided with which the image formed by the use of an image-forming apparatus for electrophotography may keep a good and uniform image density for a long period of time from the initial stage of image formation. The toner contains a toner base particle containing at least a colorant and a binder resin, silica having an average particle size of 40 nm or larger and 200 nm or smaller, and an aluminum oxide-silicon dioxide mixed oxide having an average particle size of 5 nm or larger and 25 nm or smaller. The silica and the aluminum oxide-silicon dioxide mixed oxide are externally added to the toner base particle.
