    摘要: An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The toner density of the developer is controlled so that an output value Vt of a magnetic permeability sensor approaches a target output value Vtref. In addition, the target output value Vtref is corrected in accordance with image coverage history information of output images transferred to a transfer paper and image coverage ratio history information of output images determined from the image coverage thereof and the size of the transfer paper. This history information comprises, for example, a cumulative average value of the image coverage or the image coverage ratio per transfer paper. It may also comprise a moving average value of the image coverage or the image coverage ratio per transfer material.

    摘要: An image forming apparatus connectable to a first feed tray and a second feed tray includes an image forming unit, a feed path, and a detecting unit provided on the feed path to sense recording medium jam. An identifying unit identifies a feed path and a feed tray where recording medium jam has occurred as a jammed path and a jamming feed tray. A first determining unit determines whether the image forming apparatus is connected to the second feed tray. A second determining unit determines whether the second feed tray can feed a recording medium to the image forming unit. A feeding unit feeds a recording medium from the second feed tray to the image forming unit.

    摘要: An image forming device includes a toner pattern forming unit that forms a first toner pattern and a second toner pattern downstream of the first toner pattern along a direction of advance of the transfer belt on the transfer belt. The first toner pattern is configured to include color patches of which a color density gradually differs so that, when detected by a sensor, a fluctuation of the toner density is adjusted by a feedback data. The second toner pattern is configured to prevent a cleaning blade from being twisted by a friction of an intermediate belt due to the toner lubrication.
