An image forming apparatus includes a reading table, an image reading device, an image forming device with an exposure device, and circuitry. The reading device reads a pattern on a recording medium on the table, and generates image data of the pattern. The exposure device includes a light emitting element to form an electrostatic latent image, based on which the image forming device forms the pattern. Based on first and second correction values, the circuitry calculates a third correction value to correct a light amount of the light emitting element. The exposure device includes a driving device that drives the light emitting element based on the third correction value. The circuitry sets at least two or more determination areas in each of a white area and a pattern area of the medium, and determines whether the medium has a rise based on density data in the determination areas.

Image forming apparatus and method of detecting rise of recording medium

A disclosed image forming apparatus includes an image processing device including plural image processing units; a control device configured to control the plural image processing units; and a connection unit configured to connect the image processing device to the control device. Each of the plural image processing units is connected to the control device by one of plural channels; the image processing device is connected to the control device by a first bus including the channels; and the connection unit is provided on the first bus so that the image processing device is connected to the control device by a single connection unit.

Image forming apparatus, image processing device, control device, and connection device

A plurality of control boards can be connected to each other via a high-speed bus. An image forming unit performs an image forming process, which is housed in a casing. A slot is arranged on any one of a plurality of side surfaces perpendicular to a bottom surface of the casing, which is elongated in a direction perpendicular to the bottom surface and guides the control boards to inside of the casing. The control boards are connected in parallel to each other.

An image forming apparatus includes a print-request information inputting unit, an image reading unit, a plurality of image forming units, a plurality of sheet feeding units, a memory unit and a control unit wherein the control unit reading out, when print-request information is inputted, ID information and device information from a memory unit and selects, based on the plural ID information, the device information and the print-request information, an optimum image forming unit that satisfies the print-request information. The control unit further causes the selected image forming unit to execute print processing.

Image forming apparatus including a print-request information inputting unit and image reading unit, and image forming method

An image forming apparatus includes two or more detachable components that are identical to each other and configured to perform at least part of a sequence of processes associated with forming of an image, a connection detection unit configured to detect attaching of the components, and a first control unit configured to control the sequence of processes, wherein a software-based controller for controlling one of the components is generated in response to detection by the connection detection unit of the attaching of the one of the components.
