摘要： An image forming apparatus includes a photosensitive drum, a developing device, a primary transfer part, a droplet ejecting unit and a controller. On the photosensitive drum, an electrostatic latent image is formed. The developing device forms a toner image by causing a developing agent to adhere to the electrostatic latent image. The primary transfer part transfers the toner image onto an intermediate transfer belt. The droplet ejecting unit ejects droplets onto the toner image on the photosensitive drum after forming the toner image on the photosensitive drum and before transferring the toner image to the transfer member. The controller controls an ejection area of the droplet ejecting unit in accordance with image information of the toner image.

摘要： An image forming apparatus includes: a developing device which applies a developing bias voltage obtained by superimposing an AC bias voltage onto a DC bias voltage to a photoreceptor, and develops a latent image on the photoreceptor with a developer to form a toner image. The apparatus has a toner forced discharge mode for forming a toner image for forced discharge in a first image formation area provided in a non-image formation area other than a second image formation area on the photoreceptor to forcibly discharge a toner from the developing device. When the mode is selected, an AC bias voltage at a frequency lower than that in the second image formation area is applied to the first image formation area to develop a latent image for forced discharge, to form a toner image, and a toner of the toner image is collected by a cleaning device.

Subsequently, anhydrous sulfuric acid is added in such an amount that the molar ratio is 2 to 8 with respect to a repeating unit of the intermediate product. Further, SO3 and the intermediate product are reacted with each other to sulfonate the intermediate product. The sulfonation is performed under a condition in which the temperature range is −20 to 0° C. and the total time is 5 to 30 hours. Accordingly, a sulfonated polyphosphazene derivative is obtained, in which the number average molecular weight is not less than 25,000 and the ion exchange capacity exceeds 3.0 mmol/g.
