摘要： PROBLEM TO BE SOLVED: To provide a liquid developer having an increased charge amount without increasing the amount of a charge adjusting agent or a dispersant which decreases fixing characteristics of the toner particles, and exhibiting excellent dot reproducibility while reducing image deletion or doubled image. SOLUTION: As the liquid developer includes toner particles containing a colorant and a resin dispersed in a non-aqueous solvent having an electric resistance of not less than 10 9 Ω cm, charges of charged toner particles are inhibited from moving and decrease in charging characteristics are suppressed even without adding a dispersant or a charge control agent that is an external additive causing reduction in the fixing efficiency. By using a non-aqueous solvent having a dielectric constant of 4.0 to 15.0, which means high polarity, as a carrier liquid 91Y, 91M, 91C, 91K, positive charges are easily imparted to the toner particles and more positive charges are retained. Therefore, liquid developers 100Y, 100M, 100C, 100K having a large charge amount and excellent dot reproducibility with reduced image deletion or a doubled image are obtained.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and image forming method, by which: a formed toner image can be transferred to a transfer material at high transfer efficiency regardless of the image pattern of the toner image; and a high quality transfer image free from insufficient density, nonuniform density and image deterioration can be obtained. SOLUTION: When a toner image before transfer is destaticized using a scorotron charger, two test toner images that are different in the attachment quantities of toner are formed, and the amounts of charges applied by the scorotron charger are measured. The setting of the output of the scorotron charger is adjusted so that the measured amounts of charges applied by the scorotron charger fall within predetermined ranges. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus which can achieve miniaturization by collecting a liquid developer from a developing device without using a collection means such as a conveyance pump. SOLUTION: The image forming apparatus 1 includes: a developing device 14 having a developer carrier 31 forming a toner image on an image carrier 10, developer supply parts 32 and 33 supplying the liquid developer to the developer carrier 31, and a collection path 40 collecting the liquid developer which has not been supplied from the developer supply pats 32 and 33 to the developer carrier 31; a collection container 70 capable of directly communicating with the collection path 40, and for collecting the liquid developer from the collection path 40; and a switching means 80 for switching states between a communication state in which the collection path 40 and the collection container 70 communicate with each other when the developing device 14 is attached to an apparatus body 1A and a non-communication state in which the collection path 40 and the collection container 70 do not communicate with each other when the developing device 14 is detached from the apparatus body 1A.

摘要： A wet type image forming apparatus has a primary transfer unit that transfers to an intermediate transfer body a coloring particle image formed on the surface of an image bearing member by using liquid developer. A secondary transfer unit transfers onto a recording medium the coloring particle image transferred to the intermediate transfer body. A cleaning unit recovers liquid developer remaining on the intermediate transfer body after transfer by the second transfer unit. An aggregation promoting agent addition unit is disposed on a downstream side of the secondary transfer unit in a direction of rotation of the intermediate transfer body and on an upstream side of the cleaning unit in a direction of rotation of the intermediate transfer body and adds to the surface of the intermediate transfer body an aggregation promoting agent that promotes aggregation of resin contained in the liquid developer.
