摘要： An image forming apparatus includes an image bearing member; a transfer member configured to form a transfer portion where the toner image is transferred from the image bearing member by being supplied with a transfer bias; a carrier liquid supplying portion configured to supply the carrier liquid to the transfer portion; a transfer bias voltage source capable of applying the transfer bias to the transfer portion; a detecting portion configured to detect at least one of a voltage and a current at the transfer portion; and a setting portion configured to set the transfer bias during non-image-formation on the basis of a detection result of the detecting portion when a setting bias is applied from the transfer member in a state in which the carrier liquid is in the transfer portion.

摘要： An image forming apparatus includes an image bearing member configured to bear a toner image formed using a liquid developer containing toner particles and a carrier liquid, a transfer member, an input portion into which information on a kind of a recording material is inputted, an adjusting device configured to adjust an amount of the carrier liquid of the toner image, and an executing portion configured to execute an operation of the adjusting device depending on the information when the toner image is in the adjusting position. The executing position executes either of a plurality of operations including a first operation in which the amount of the carrier liquid of the toner image is increased, a second operation in which the amount of the carrier liquid is decreased, and a third operation in which the amount of the carrier liquid is not adjusted.

摘要： An image forming apparatus which has a constitution of a tandem type and an intermediary transfer type and which is capable of adjusting a liquid amount of a carrier liquid layer formed on an intermediary transfer belt depending on an image forming mode.
In a case of a full-color mode (YES of S2), a controller sets an operation mode of a liquid amount adjusting device at a "removal mode" (S4). In a case of a monochromatic mode (NO of S2), the controller sets the operation mode at a "supply mode" (S6). In the removal mode, a carrier liquid in the carrier liquid tank is not carried on a feeding roller, so that the carrier liquid is removed from the belt by the feeding roller. In the supply mode, the carrier liquid drawn up from the carrier liquid tank by a supplying roller is supplied to the belt via the feeding roller. Thus, liquid amount adjustment of the carrier liquid layer depending on the image forming mode is carried out, so that an occurrence of improper transfer due to a shortage of the carrier can be suppressed while suppressing an excessive carrier during full-color mode.
