摘要： Timing information for use to determine the timing to discharge a sheet from an image forming apparatus is transmitted. The timing information is relayed, by being edited repeatedly, from a first sheet processing apparatus connected directly with the image forming apparatus to a second sheet processing apparatus which actually processes the sheet. The timing information is edited on each sheet processing apparatus by considering, for example, transit time of the sheet, processing time of the sheet, preparation time for the sheet to get ready to be processed, and the like. The second sheet processing apparatus transmits the timing information to the image forming apparatus. The image forming apparatus determines the discharge timing of the sheet based on the received timing information and discharges the sheet with the determined discharge timing.

The sensor unit includes a correction mechanism to correct an output signal of the sensor unit by changing an external-input voltage, based on relationship data between an output voltage change of the sensor unit and a toner-concentration of unused developer, to control the toner supply amount when the toner-concentration of the two-component toner deviates a predetermined amount from the toner-concentration of the unused developer. The sensor unit is configured to detect the toner-concentration of the unused developer from unused two-component toner based on a change in the external-input voltage.

摘要： A developing unit supplies toner from a developing roller to an electrostatic latent image formed on an image carrier, and creates a visual image. A forced consumption unit causes, when a proportion of number of pixels used for forming the electrostatic latent image for a maximum image effective-width is equal to or less than a predetermined value, a forced consumption of toner by an amount corresponding to a difference between a toner amount corresponding to the number of pixels and a predetermined toner consumption amount. The forced consumption unit adds toner of an amount used in the forced consumption to an amount of toner to be supplied in a next imaging process.
