摘要： The present invention aims to provide an image forming apparatus and the like that perform a highly-accurate tone correction in a relatively short time and includes the following: a pattern former, with use of each image forming unit, on a sheet, forming tone patches in the main or sub scanning direction (41k,c,y,m) and aligning markers, which indicate positions of the tone patches, in the same direction as the tone patches (42k,c,y,m); a pattern reader reading the sheet with the tone patches and markers formed thereon; a coordinate determiner determining coordinates of the tone patches in the direction of the aligned tone patches based on the read markers (42k,c,y,m); a density determiner determining densities of the tone patches (41k,c,y,m) read based on the determined coordinates; and an updating part updating the tone correction table based on relationships between the determined densities and tone levels.

摘要： A tandem-type color image forming apparatus forms a toner pattern and toner markers on an intermediate transfer member. Tone levels in the toner pattern vary in a sub scanning direction, and the toner markers which are a same color with the tone pattern each oppose, in a main scanning direction, a different one of the tone level portions in the toner pattern, each tone level portion representing a different one of the tone levels. Positions of the toner markers in the sub scanning direction are determined to detect densities in the toner pattern corresponding to the determined positions. Tone of image data is corrected in an image formation based on a relationship between the densities and the tone levels corresponding to the determined positions.

摘要： A clean environmental actuator is less in weight, height in transverse section and compact in construction, even with ensuring accurate position control and conformable to high speed operation and high acceleration/deceleration. Both a bed and a slider are stowed in an enclosure and packings are in T-slots in side walls of the bed to seal clearances between the bed and the enclosure. The enclosure is composed of an end bracket to cover one end of the bed, a motor bracket to cover another end of the bed, a pair of side coverings to enclose the side surfaces and tops of the side walls of the bed, a sealing panel to cover an upward opening between the side coverings, and a table covering to overlay an area of the sealing panel lying on the slider and side areas of the table bulging out from side edges of the sealing panel.
