An image forming apparatus includes a fixing section, a de-curling section, and a control section. The de-curling section has a de-curling nip portion that presses a sheet to correct a curl caused in the sheet, and a corrective force thereof to press the sheet changes at least in two steps. The control section increases the conveyance speed of the sheet after a rear end of the sheet has passed the fixing nip portion when the de-curling section supports by sandwiching the sheet with a weakly-pressing force. When the de-curling section supports by sandwiching the sheet with a strongly-pressing force, the controller increases the conveyance speed of the sheet after the rear end of the sheet has passed the fixing nip portion and the de-curling nip portion.

Provided is a method for forming an image containing the steps of: supplying a clear toner on a surface of an image forming support; heating the supplied clear toner on the surface of the image forming support to melt; close contacting the surface of the image forming support supplied with the clear toner with a belt; and cooling the clear toner in a state of close contacting with the belt so as to form a clear toner layer on the image forming support, wherein the aforesaid clear toner contains at least a resin formed with a polymerizable monomer represented by Formula (1) and a vinyl monomer, Formula (1): H2C═CR1—COOR2, wherein R1 represents a hydrogen atom or a methyl group; and R2 represents a chain alkyl group having 12 to 22 carbon atoms, or a cyclic alkyl group.

The control portion controls the sheet adjusting portion to alternately convey the sheet of paper fed from the sheet-feeding path for single-side printing and the sheet of paper fed from the sheet-feeding path for duplex printing to the image forming portion during the duplex printing mode. Images are alternately formed on the front surface of each of the sheets of paper and the back surface of each of the sheets of paper when three sheets of paper are conveyed to the image forming apparatus and they are left therein. The control portion controls the sheet conveying portion to release the contact of the conveying rollers after it is detected that the sheet of paper reaches the sheet adjusting portion.
摘要:
According to the present invention, in changing the concentration of a treatment solution supplied to a substrate, a volume of an existing treatment solution in a tank connected to a treatment solution supply section for supplying the treatment solution to the substrate is first measured. Based on this measured value, a minimum drain volume of the existing treatment solution to be drained out from the tank and a supply volume of either a treatment solution with a predetermined concentration or a diluting fluid to be supplied into the tank is calculated respectively in order to change the treatment solution in the tank to be in an intended volume and to have an intended concentration. Then, the calculated drain volume of the existing treatment solution is drained out from the tank. Meanwhile, the calculated supply volume of either the treatment solution with the predetermined concentration or the diluting fluid is supplied into the tank. According to the present invention, since the drain volume in changing the concentration of the treatment solution can be reduced, a wasteful consumption volume of the treatment solution is reduced accordingly so that cost reduction can be realized. Moreover, the time required for the concentration change can be shortened.
