A wireless communication apparatus is provided for selecting an optimum frequency even when radio wave conditions have changed. A wireless communication apparatus provided with a frequency selector for selecting an optimum frequency for establishing a link for mutually transmitting and receiving has a transceiver for transmitting radio waves to another wireless communication apparatus and receiving from the other wireless communication apparatus radio waves responding to those transmitted radio waves, a quality analyzer for analyzing communication quality indicating the condition of the link from the received radio waves, and a quality updater for updating the analyzed communication quality on the basis of time elapsed from when the radio waves were received. In addition, the frequency selector selects the optimum frequency on the basis of the updated communication quality.

Disclosed is an image forming apparatus whereby waiting time (downtime), which is required for forming an image by automatic adjustment relating to image formation density or image formation position, is made shorter than in the prior art. When an image having a size equal to or less than a prescribed size is formed is formed in this apparatus, the image to be formed is placed on an image carrier in such a manner that a vacant area for forming an adjustment pattern can be reserved on the image carrier. As a result, automatic adjustment relating to image formation density or image formation position can be executed while an image is formed.

This invention provides an image forming apparatus capable of shortening the user's print waiting time as much as possible when it is determined that image adjustment is necessary during the image forming operation, and a control method therefor. To accomplish this, in a color image forming apparatus including a plurality of image forming stations which form toner images with a plurality of toners on the basis of a job, it is discriminated whether adjustment processing is necessary during a continuous image forming operation based on the job. If it is discriminated that adjustment processing is necessary, it is determined whether each of the image forming stations has a non-operating time enough to execute the discriminated adjustment processing during the image forming operation. The image forming station determined to have a non-operating time enough to execute adjustment processing executes the discriminated adjustment processing during the non-operating time.

An image-forming apparatus includes a rotatable photoreceptor carrying a toner image thereon, a rotatable intermediate transfer member, a primary transfer device facilitating primary transfer of the toner image from the photoreceptor onto the intermediate transfer member, a secondary transfer device facilitating secondary transfer of the toner image from the intermediate transfer member onto a sheet, and a controller controlling rotation speed of the intermediate transfer member. The controller sets the rotation speed at a first speed during primary transfer. After primary transfer and a delay period, the controller changes the rotation speed to a second speed. The controller determines which rotation of the intermediate transfer member to change the speed.

An image forming apparatus such as a copier with a detachable process cartridge is provided with a first memory for storing the number of copying operations; a count renewing unit for increasing the count of the first memory and a second memory in the process cartridge, at each copying operation, a comparator for comparing the counts in the first and second memories, and a controller for determining a process condition specific to the process cartridge in case the counts do not mutually coincide. The service life of the process cartridge can be more precisely judged, and the process condition can be more appropriately determined for each process cartridge.

An optical information recording apparatus includes an emission output information acquisition section for acquiring information about a drive current employed for controlling a beam output from an information recording section; a cooling determination section for determining whether to cool the information recording section in accordance with the information about the emission output acquired by the emission output information acquisition section; and a cooling execution section for cooling the information recording section when the cooling determination section has determined that cooling should be performed.
摘要:
An image forming apparatus in which the intensity of a light beam used to form a latent image is switched in response to a change in resolution. A laser emits a light beam for forming a latent image on a photosensitive drum. A polygon mirror scans the emitted light beam. BD sensors detect the scanned beam. A timing controller selects the preferable timing from a storage device table according to the intensity of the light beam or the resolution when controlling the light emission timing of the lasers in response to a detection of timing of the detected light beam.
