The present invention provides a particle dispersion liquid including

Particle dispersion liquid, particles, particle dispersion liquid cartridge, process cartridge, image forming apparatus, and image forming method

A plurality of beams scan the photosensitive body or the like so that a high quality image whose streak is not recognized by a human eye can be formed. 2m lines are formed simultaneously in Nth time, (N+1)-th time, and (N+2)-th time scannings respectively. At this point, the m lines are fed in a sub-scanning direction at each termination of one-time scanning, and the next scanning is performed. Accordingly, a region which is exposed twice between the scannings is generated at an m-line period.

Method and apparatus for reducing the visibility of streaks in images generated using scanning techniques

The invention provides an image formation device based on the electrophotographic system, whereby, when an outputted image varies from the halftone area to the background area in the sub-scanning direction, the density reduction of a rear end area of the halftone area that borders on the background area can be prevented, by means of simplified and small-scale processing. In this image formation device, a backward edge of the halftone area that borders on the background area is extracted, and an image data value of the background area including m pixels after this backward edge in the sub-scanning direction, of input image data Si, is modified to a setting value with correction data. The setting value is set to a value slightly lower than the threshold value corresponding to the dot area coverage of an image recurrence start point. If there is a halftone area whose image data value given by input image data Sib is greater than the threshold value, or a background area whose image data value is greater than the setting value, in an area including m pixels in the sub-scanning direction after the backward edge of the halftone area given by input image data Sia, the value of the image data with regard to that area will not be modified, and only the value of the image data with regard to the area from the backward edge of the halftone area to that area will be modified to the setting value.

It is made possible to prevent decrease in the density due to the image output characteristic of the image output unit in the subscanning direction by means of a method according to the present invention capable of real-time processing without causing the circuit capacity and the memory to be increased. In an image input unit,, the input image data is acquired so that its time series direction becomes a direction indicated by an arrow,corresponding to the subscanning direction of an image output unit,. The input image data from the image input unit,is corrected in accordance with the image output characteristic of the image output unit,in the subscanning direction. The image data after the correction is rotationally processed so that its time series direction becomes a direction indicated by an arrow,corresponding to the main scanning direction of the image output unit,. The image data after the rotary processing is sent to the image output unit

Image processing device and image forming apparatus

To prevent the density of a low density part when an output image varies from the low density part to a high density part in a vertical scanning direction from being lowered without expanding an image forming apparatus or an image output device and increasing the cost, an image processing section first extracts an edge picture element of the low density part which is in contact with the high density part when an image output based upon input image data Si varies from the low density part to the high density part in the vertical scanning direction or from the high density part to the low density part in the vertical scanning direction. Next, the image processing section reads the number a of picture elements to be corrected and pixel value corrected quantity b from a look-up table based upon the low density part pixel value L and the high density part pixel value L before and after the edge picture element, corrects the pixel value of the input image data Si and sends the corrected output image data So to an image output section.

In view of realizing higher resolution in the sub-scanning direction and achieving high precision and high quality image formation without generating ununiform distribution of exposure, a scanning surface of a photosensitive material is scanned with an optical beam on sequential parallel linear scanning lines with a predetermined angle for the main scanning direction to form an exposed image thereon.
