摘要： A toner, such as an electrostatic latent image developing toner and a MICR toner, has an even charge distribution, and exhibits balanced charging characteristics without decreases in frictional electrification or increases in charge, as well as superior fluidity, environmental independence, and durability. This is achieved by treating toner particles, which include binder resin and magnetic particles, with an external additive particle that is one of: a combination of rutile-type titanium oxide and anatase-type titanium oxide; and rutile-type titanium oxide that falls in a range of 5 to 10% by volume when a total volume of the toner is regarded as being 100%.

摘要： An optical imaging system (18) radiates a light image of an original document (13) onto a photoconductive drum (16) to form a first electrostatic image. The light image is also focussed on a photosensor array (44) which produces electrical signals corresponding thereto. These signals are fed through a contour compensation circuit (49) which increases the contrast at the black-white transition points of the image and thereby at the contours of the image areas. The contour compensated signals are radiated by an array of light emitting elements (46) onto the drum (16) to form a second electrostatic image which is superimposed on the first electrostatic image. The result is an increase in the apparent resolution of a copy or reproduction produced by applying toner to the drum (16) to form a toner image and transferring and fixing the toner image to a copy sheet. The arrays (44) and (46) may be used separately for facsimile transmission and reception respectively.
摘要翻译：光学成像系统（18）将原稿（13）的光图像照射到感光鼓（16）上以形成第一静电图像。光图像也聚焦在产生与之对应的电信号的光传感器阵列（44）上。这些信号被馈送通过轮廓补偿电路（49），其增加了图像的黑白转换点处的对比度，从而增加了图像区域的轮廓。轮廓补偿信号由发光元件阵列（46）辐射到滚筒（16）上以形成叠加在第一静电图像上的第二静电图像。结果是通过将墨粉施加到鼓（16）而形成调色剂图像并将调色剂图像转印并固定到复印纸上而产生的复印或再现的表观分辨率的增加。阵列（44）和（46）可以分别用于传真发送和接收。

摘要： A color document or color video information is inputted to a system which corrects the color of the images scanned or inputted by using data indicative of the conditions under which the color document or color video information was prepared. Color compensation coefficients are used to correct for color distortions that might have occurred in the color document or in the color video information. The color distortions of the input document or those of the color video signal relative to an original are provided as data values of a function of three primary color separation signals, so that color compensation may be performed by an inverse processing of the same data function. This allows for a more accurate and faithful reproduction of the color image.
