摘要： A driving force produced by a first driving motor is transmitted to a developing roller and an intermediate application roller by a first drive transmission unit, and the developing roller and the intermediate application roller are rotated as a result. The developing roller and the intermediate application roller thus take the first driving motor as a drive source, and receive the driving force from the first driving motor via the same first drive transmission unit. As a result, the phases of the fluctuation in a rotational component of the first driving motor and the cyclic fluctuation of gear interlocking match, which reduces a rotational velocity difference between the developing roller and the intermediate application roller.

摘要： Developer is recovered by a development unit, a first squeeze unit, a second squeeze unit, and a photoreceptor cleaning unit, but the developer recovered by the development unit or the first squeeze unit has a relatively high concentration, and is therefore returned to a stirring tank for reuse. The developer recovered by the second squeeze unit or the photoreceptor cleaning unit has a relatively low concentration, and is therefore accumulated in a buffer tank separate from the stirring tank to prevent the toner concentration in the stirring tank from decreasing.

摘要： An image forming apparatus of the invention includes a carrier solution application roller that rotates centering on a rotary shaft and applies a carrier solution to a transfer roller after an image of a liquid developer including toner and the carrier solution is transferred to a transfer medium, a transfer roller cleaning roller, supported by a cleaning member support portion through a rotary shaft, which removes toner remaining in the transfer roller, and a carrier solution application roller of which the amount of movement is larger than the amount of movement of the transfer roller cleaning roller when the cleaning member support portion is rotated. Even when the transfer roller moves, satisfactory cleaning properties are secured without breaking a mutual positional relationship by facilitating mutual positioning between the transfer roller and the transfer roller cleaning roller.

摘要： In a fixing device incorporated in an image forming apparatus and operable to fix a toner image on a recording medium, a first rotative member and a second rotative member form a nip portion therebetween, at which the toner image is fixed on the recording medium. A separator separates the recording medium, which has been passed through the nip portion, from one of the first rotative member and the second rotative member. The separator is provided with a first guide face extending in a first direction to guide the separated recording medium to an inlet of a subsequent stage of the image forming apparatus. The first guide face is provided with a rib extending in the first direction.
