摘要： An image writing device includes an exposure unit including an exposure head, writing an image onto an image bearing surface of a photoconductor by causing the exposure head to repeatedly expose; and a write control unit transmitting image data to be written by the exposure unit to the exposure unit on a one-line basis. Further the write control unit generates a write cycle reference signal having a cycle corresponding to writing resolution, counts a clock by a predetermined count value, generates a write cycle signal by delaying the write cycle reference signal by a time period, generates a data request signal to request transmission of one line of the image data to a controller unit based on the write cycle signal, and stores the one line of the image data transmitted from the controller unit.

摘要： An image writing device includes an exposure device to repeatedly expose a surface of an image bearer along a main-scanning direction during an image forming period to write an image on the image bearer, a speed change detector to detect a change in moving speed in a sub-scanning direction of the surface of the image bearer, a first signal generation circuit to generate a first signal, an image forming period signal generation circuit to generate an image forming period signal synchronously with the first signal, a second signal generation circuit to generate a second signal, the second signal initially appearing in the image forming period being in synchronization with the first signal, and a line synchronization signal generation circuit to generate a line synchronization signal synchronously with the second signal and transmit the line synchronization signal to the exposure device during the image forming period.

摘要： 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.
