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.

A sheet conveying device includes a sheet detection unit and a position adjusting mechanism. The position adjusting mechanism is disposed on a downstream side of the sheet detection unit in a sheet conveying direction in the sheet conveying path, includes an adjusting roller pair, and performs skew correction and positional displacement correction of a sheet, while conveying the sheet. The sheet conveying path includes a first conveying roller pair disposed on an upstream side of the position adjusting mechanism in the sheet conveying direction, and a curved part disposed between the adjusting roller pair and the first conveying roller pair, which curves in an S shape so as to be convex in a front and back side direction of the sheet alternately at different positions in the sheet conveying direction. The adjusting roller pair nips and conveys the sheet together with the first conveying roller pair.

An endless belt includes a polyamide imide resin layer in which a content of at least one solvent selected from a solvent group A consisting of a urea solvent, an alkoxy group-containing amide solvent, and an ester group-containing amide solvent is from 0.005 parts by weight to 3 parts by weight with respect to 100 parts by weight of the polyamide imide resin layer.

A relationship 150≦Rs (Ω)/Rm (Ω)≦4000 is established in an environment of a temperature of 15° C. and a humidity of 10% in a case where a surface resistance of a transfer roller is Rs (Ω) when a current is fed between a pair of electrodes facing each other in an axial direction of the transfer roller and arranged on a surface of the transfer roller with an interval of 5 mm therebetween, the electrodes having a width of 20 mm in a circumferential direction of the transfer roller in a state of being arranged on the transfer roller, and in a case where a combined resistance of a first layer and a second layer is Rm (Ω) when the current is fed from a core portion to an outer peripheral surface of the second layer.

An image forming apparatus includes an image bearing drum; a drum charging member at a charging position opposed to the drum, with a charging bias; a developing member for developing an electrostatic image formed on the drum with toner, with a developing bias; a transfer member for transferring a toner image from the drum onto a sheet, with a transfer bias; a transfer bias source for outputting transfer bias; and a controller for effecting control to start raising of the transfer bias so as to correspond to timing at which an area of the drum passing at a timing of starting of raising of the charging bias passes the transfer position and to complete the raising of the transfer bias so as to correspond to timing at which an area of the drum passing at a timing of completion of raising of the charging bias passes the transfer position.

An image forming apparatus includes a controlling unit that executes a supply mode in which a supply toner image is formed on an image carrying member and supply toner is supplied to a contact portion between a cleaning member and the image carrying member. The controlling unit performs control such that the toner amount that is supplied to a contact portion in a supplying operation is smaller when the surface smoothness of a transfer material corresponds to a second roughness than when the surface smoothness of the transfer material corresponds to a first roughness, the second roughness being greater than the first roughness.
