摘要： PROBLEM TO BE SOLVED: To form an image at an accurate position by adjusting the timing of the conveyance of a recording sheet in the case of the use of the recording sheet with a tab or the like attached to its leading end. SOLUTION: In an image forming section, a toner image is formed by selectively attaching toner to a latent image by an electrostatic potential difference, and the toner image is then conveyed to a secondary transfer section opposite to the transfer roll 12 while held on an intermediate transfer body 11. The recording sheet P is conveyed from a sheet tray 13 or both-sided conveyance path 18. Upon the detection of the trailing end of the recording sheet P by a sheet sensor 31, a signal is input to a controller 32, and the conveyance is temporarily stopped with a predetermined timing. Thereafter, the rotation of a registration roll 20 is resumed matching the timing of the conveyance of the toner image held on the intermediate transfer body. Thus, the recording sheet is sent to a secondary transfer section with a proper timing. COPYRIGHT: (C)2006,JPO&NCIPI
