摘要： PROBLEM TO BE SOLVED: To provide an image adjusting method and an image forming apparatus capable of efficiently adjusting color-matching in a short period of time while suppressing the useless consumption of developer etc., in the case of adjusting the color-matching, and to provide a computer program. SOLUTION: In the whole color-matching adjustment area (100 dots), a density mean value is detected in a measuring area (nearly 10 dots) corresponding to the pitch of a detection pattern, and then, a value proposed as a correction value for an exposure timing of an adjustment image is obtained from a maximum detection value within the color-matching adjustment area. By performing the aforesaid processing with respect to two kinds of detection patterns having different pitches, two values proposed as the correction value are obtained, then, the correction value for the exposure timing is obtained from the value matched in both detection patterns.

摘要： PROBLEM TO BE SOLVED: To provide an image adjusting method for an image forming apparatus capable of saving developer for forming an image for the density detection required for a color-matching adjustment. SOLUTION: As for the image adjusting method, among a plurality of color components, a plurality of adjusting images as adjusting objects having color components other than the reference color components are separately overlaid on a plurality of reference images having reference color components, and then, transferred on a transfer medium so as to form the adjusting image, and then, the density of the formed adjusting image is detected, and the adjustment of the position for forming the image having other color components is performed based on the detected density in the moving direction (S1) of the transfer medium and in a direction (S2) vertical to the moving direction, respectively. As for the adjustment of the image forming positions in the moving direction (S1) and the vertical position (S2), an area for forming the adjusting image for the former adjustment of the image forming position is made larger than an area for forming the adjusting image for the latter.

摘要： PROBLEM TO BE SOLVED: To form each of images for image quality discrimination and for color matching without wasting a developer, and to efficiently perform color matching in a short period of time.
SOLUTION: An image forming apparatus forms images based on a plurality of color components respectively and transfers the formed images to a transfer medium to form an image for image quality discrimination (S1) and discriminates (S3) the image quality of the image for image quality discrimination on the basis of a detected density (S2) of the image for image quality discrimination and superposes adjustment object images of color components other than a reference color component out of the plurality of color components, which are adjustment objects and a reference image of the reference color component onto the transfer medium to transfer them thereto and forms an image for adjustment, and detects the density of the image for adjustment and adjusts image formation positions of the other color components being the adjustment objects on the basis of the detected density (S4). The image for adjustment is formed (S4) after the image for image quality discrimination is formed (S1).

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive image forming apparatus which prevents developer falling on an outer cover from further falling outside through a gap and, therefore, prevents a floor or paper stored in a paper feed desk device from being soiled.
SOLUTION: A front cover 105 has receiving portions 53 and 54 for holding toner caused to fall. The receiving portions 53 and 54 are disposed near an image forming device main body and below a processing unit (developing devices 2a to 2c, process unit 80) attached/detached to/from the image forming device main body when the cover 105 is opened/closed. With regard to a pedestal for placing the processing unit thereon, an inner cover 68 is disposed on an edge opposite the front cover 105 such that the pedestal further projects in a direction in which the processing unit is taken out than the edge of the pedestal in the receiving portion 54. The inner cover 68 is disposed nearer to the front cover in a closed state than the placed processing unit and higher than the receiving portion 54.

摘要： PROBLEM TO BE SOLVED: To compactly contain a pick up means in the side face of an image processing device even if the pick up means is provided with a protective cover.
SOLUTION: The protective cover 281 turnably provided on the side face side of an image formation device and the pick up means 280 are provided with hook sections 34 and 30 respectively. The protective cover 281, the turning centers G and H of the pick up means 280 and the hook sections 34 and 30 are arranged such that when the protective cover 281 is made to turn from an operating position (a) toward a position where the pick up means is contained from in the side face of the image processing device, the hook sections 34 and 30 are engaged only in an area S from a specified locus cross section 3x to the side face side of the image formation. In the case where the pick up means 280 does not feed a sheet, the pick up means 280 is made to stop at an engagement starting position (a), where the hook section 30 becomes the locus cross section 3x, and in the case where the pick up means 280 feeds a sheet, the pick up means 280 moves to the operating position (c). The protective cover 281 is constituted so as to turn interlocking with the turning of a paper sheet feeding tray, which is not shown in the figure, turnably provided on the side face side of the image formation device.
