Patent ID: 8000640

Claim:
An image forming apparatus, comprising: an image supporting member; an image forming mechanism which is adapted to form an electrostatic latent image on the image supporting member; a developing section which is adapted to develop the electrostatic latent image formed on the image supporting member with a liquid developer including a toner so as to form a toner image; a transferring section which is adapted to transfer the toner image formed by the developing section onto a recording material; an input portion which is adapted to input a property of the recording material; a toner amount control portion which is adapted to control an amount of the toner of the toner image depending on the property of the recording material inputted by the input portion; a toner amount measurement section configured to determine an amount of the toner of the toner image; a charge applying section which is adapted to apply to the toner image, whose amount of the toner has been determined by the toner amount measurement section, a charge of opposite polarity to a charge polarity of the toner image between a developing position defined by the developing section and a transferring position defined by the transferring section; a storing section for storing a data table defining a relationship between charges of opposite polarity to be applied by the charge applying section, and an amount of toner of a toner image; a charge amount control portion adapted to determine an amount of the charge to be applied by the charge applying section, by referring to the data table based on the amount of the toner of the toner image, which has been determined by the toner amount measurement section; and the charge amount control portion configured to control an amount of the charge to be applied by the charge applying section so that as an amount of toner in a toner image increases, the charge applied to the toner by the charge applying section is increased.
