摘要:
An image processing apparatus includes in one version an input device for inputting digital image data, a contour process circuit for emphasizing contour data in the digital image data form the input device, a circuit for smoothing the digital image data from the input device, and an output device for selectively outputting the digital image data input from the input device and subjected to different image processes in different designated areas. Densities of the contour and non-contour data can preferably be controlled independently of each other.

In an apparatus including the detachable unit, when reading individual information of the detachable unit, a first label for generating a reference signal for reading individual information and a second label representing the individual information are arranged on a surface of the detachable unit, with a first label reading unit, the reference signal is generated while reading the first label in a predetermined direction, and with a second label reading unit, the individual information of the detachable unit contained in the second label is read in synchronous with the generated reference signal. Read individual information is stored, and whether a mounted detachable unit is new or used is recognized based on a comparison of individual information read from the detachable unit with stored individual information.

A sheet skew-correcting device includes a sheet-conveying rotation body for conveying a sheet, a skew-correcting member that contacts an end of the sheet conveyed by the sheet-conveying rotation body for correcting skew of the sheet, and a driving unit for moving the skew-correcting member. The skew-correcting member moved in a sheet-conveying direction by the driving unit contacts the end of the sheet conveyed in the sheet-conveying direction by the sheet-conveying rotation body, so as to correct the skew of the sheet.
摘要:
An image forming apparatus has a water content determination apparatus that can precisely determining a water content in a medium regardless of an environment where the image forming apparatus is installed. The water content determination apparatus has a detection device that outputs a first signal while the medium is absent in an electrostatic capacitance region formed in a path where the medium is conveyed and outputs a second signal while the medium is present in the electrostatic capacitance region. The temperature in the image forming apparatus is determined based on the first signal. The water content in the medium is determined based on the second signal and the temperature determined by the temperature determination device.

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.
