  • Patent number: 9753397
    Abstract: An image forming apparatus includes: a first optical head group including first optical heads arranged in a sub-scanning direction; a second optical head group including second optical heads arranged in the sub-scanning direction and overlapping the first optical head group in a main scanning direction; a detector that detects displacement amounts between the first optical heads and the second optical heads; and a controller that performs registration based on the detection by the detector. The controller performs, with one of the first optical heads as a reference, registration on the other first optical heads, performs, with one of the second optical heads as a reference, registration on the other second optical heads, and performs registration between the first optical head group and the second optical head group based on a displacement amount between one of the first optical heads and one of the second optical heads.

  • Patent number: 9563143
    Abstract: An image formation method includes: a first image formation misregistration correction processing that causes each image formation unit to form a misregistration amount detection pattern, obtains an image formation misregistration amount by detecting the patterns, and corrects an image formation misregistration based on the obtained image formation misregistration amount; comparison processing that compares a previous image formation misregistration amount with a latest image formation misregistration amount; and a second image formation misregistration correction processing that causes each image formation unit to form new misregistration amount detection patterns, obtains a new image formation misregistration amount by detecting the new patterns and corrects the image formation misregistration based on the obtained new image formation misregistration amount when receiving a new print job and if a difference between the previous image formation misregistration amount and the latest image formation misregistr

  • Patent number: 9207556
    Abstract: An image formation apparatus includes an image carrier, a charge device configured to charge the surface of the image carrier, a development device configured to pass a developer to an electrostatic latent image on the image carrier formed by exposure, a transfer device configured to transfer a developer image formed on the image carrier onto a medium, a remover device configured to remove the developer on the image carrier, and a controller configured to control a cleaning mode for removing extraneous matter adhered to the surface of the charge device at a time other than the time for the process of exposing the image carrier, and to change the execution frequency of the cleaning mode in accordance with an environmental condition.

  • Publication number: 20120230596
    Abstract: To provide a technology with which it is possible to protect the privacy of a person whose image is captured by a camera and to easily check whether or not the camera is operating properly. An image processing apparatus includes: an image compressing unit that acquires compressed image information by compressing image information that is outputted by a camera and outputs the acquired compressed image information; an image analyzing unit that acquires analyzed information by analyzing the image information that is outputted by the camera and outputs the acquired analyzed information; an output switching unit that outputs, as output information, either one of the compressed image information that is outputted by the image compressing unit and the analyzed information that is outputted by the image analyzing unit; and an output unit that outputs, to another apparatus, the output information that is outputted by the output switching unit.
