    • A method for producing a toner including periodically forming and discharging liquid droplets of a toner composition liquid containing at least a resin, a releasing agent and a colorant from a plurality of nozzles formed in a thin film which is provided in a reservoir for the toner composition liquid, by vibrating the thin film using a mechanically vibrating unit, and forming toner particles by solidifying the liquid droplets, wherein the forming toner particles comprises primarily drying the liquid droplets under a stream of dry gas containing an organic solvent whose partial pressure is equal to or higher than 1/10 of a saturated vapor pressure thereof but is equal to or lower than the saturated vapor pressure, the saturated vapor pressure being that at a drying temperature; and secondarily drying the primarily dried liquid droplets for solidification while the organic solvent is being evaporated.

    • An image forming apparatus has a memory, an image forming unit, an intermediate transfer member, a density detector, a background density measurer, a test patch controlling unit and a density correcting unit. The density detector detects the density of the intermediate transfer member. The background density measurer stores background density, in the memory in correspondence with position information on the intermediate transfer member at a predetermined timing before a calibration for adjusting image formation density. The test patch controlling unit causes the image forming unit to form a test patch, on the intermediate transfer member while the intermediate transfer member is driven at a predetermined speed. The density correcting unit executes the calibration to adjust image formation density according to a difference between the background density stored in the memory when executing the calibration and corresponding to the position and density of the test patch.
    • 图像形成装置具有存储器,图像形成单元,中间转印构件,浓度检测器,背景浓度测量器,测试块控制单元和浓度校正单元。 密度检测器检测中间转印部件的密度。 背景浓度测量器在调整图像形成密度的校准之前的预定定时将与中间转印部件上的位置信息相对应的记录体中的背景浓度存储。 测试片控制单元使图像形成单元在中间转印构件上以预定速度驱动中间转印构件时形成测试片。 密度校正单元执行校准,以在执行校准时根据存储在存储器中的背景浓度之间的差异来调整图像形成密度,并且与测试贴片的位置和密度相对应。
