To provide a treatment agent solution coating apparatus that can prevent the occurrence of the skew of a sheet and the coating unevenness of a previous coating solution.
A treatment agent solution coating apparatus 4 includes treatment agent solution coating means 13, 14, recorded medium transfer means 8 and buffer means 12, and sends a long recorded medium 6 into an image forming apparatus 5 connected. The recorded medium transfer means 8 has a function for transferring the recorded medium 6 in a predetermined direction and a function for fixing it in a predetermined position. The treatment agent solution coating apparatus 4 configures an image forming system 1 for positioning the buffer means 12 in a transferable position after passing the recorded medium 6 to the apparatus 4 and the image forming apparatus 5, performing inching for forming a state where an imageable tension is applied to the recorded medium 6 on the transfer path, and then forming an image. When positioning the buffer means 12 in the transferable position, the slip of the recorded medium 6 is detected by using a transfer speed of the recorded medium transfer means 8 and a movement speed of the buffer means 12, and the transfer speed of the recorded medium 6 in the inching and image formation is corrected based on the detection value.
