Claim:
1. An image forming system of a tandem type comprising: a first image forming apparatus disposed on an upstream side in a sheet conveying direction; a second image forming apparatus disposed on a downstream side in the sheet conveying direction; and an intermediate conveying apparatus which is disposed between the first image forming apparatus and the second image forming apparatus and conveys a sheet conveyed from the first image forming apparatus to the second image forming apparatus using a sheet conveying member, wherein when forming images on both sides of a sheet, the first image forming apparatus forms an image on one side of the sheet and the second image forming apparatus forms an image on the other side of the sheet, and the image forming system further comprising: a first detecting portion that detects a temperature of the sheet conveying member in the intermediate conveying apparatus; an adjusting portion that calculates a target temperature of the sheet conveying member using a detection result of the second detecting portion, and adjusts the temperature of the sheet conveying member so as to be kept at the target temperature, according to a detection result of the first detecting portion, such that a size of the image formed on one side of the sheet by the first image forming apparatus matches a size of the image formed on the other side of the sheet by the second image forming apparatus.
