摘要： Image data of 256 gradations is converted into that of 4 gradations which can be recorded by a recording head, at a pseudo-halftone processing unit and the converted image data is supplied to a head driving unit. A control signal selector selects a control signal A from a control signal A setting unit when the image data is a natural image, and a control signal B from a control signal B setting unit when the image data is a character or a line drawing. The head driving unit generates an electric signal used to drive the recording head on the basis of gradation information from the pseudo-halftone processing unit and the control signal A or B. With this operation, when the image data is a natural image, recording is carried out with a pixel dot for image formation excellent in gradation property, and when the image data is a character or a line drawing, recording is carried out with a pixel dot for image formation which causes no jaggy or blur to be generated at hatched portions and the like.
摘要翻译： 256个灰度的图像数据被转换为可由记录头在伪半色调处理单元记录的4个灰度的图像数据，并将经转换的图像数据提供给头驱动单元。当图像数据是自然图像时，控制信号选择器从控制信号A设置单元选择控制信号A，以及当图像数据是字符或线条图时来自控制信号B设置单元的控制信号B. 头驱动单元根据来自伪半色调处理单元和控制信号A或B的灰度信息产生用于驱动记录头的电信号。通过该操作，当图像数据是自然图像时，记录是进行具有优异的灰度特性的图像形成的像素点，并且当图像数据是字符或线条画时，利用图像形成的像素点进行记录，从而在阴影部分不产生锯齿或模糊等等。

摘要： Apparatus for fixing toner image on a toner image supporting member in electrophotographic copying machine is disclosed. The fixing apparatus includes three rotary rollers which are in contact with each other under the action of pressing means. One of the three rollers has a smaller diameter than the other two rollers. Two rollers with which the toner image supporting member comes into contact are disposed in such a manner that the axes of the two rollers intersect each other and the portion at which the two rollers contact each other or are closest to each other forms a straight line relative to the direction of roller axis. According to one embodiment of the invention, the remaining one roller with which the supporting member does not contact, is formed as a crown roller, that is, a roller which has its largest diameter at the middle portion of the roller.
