Abstract:
1. An image forming apparatus, comprising: a transferring section that transfers an image to an image receiving medium at a given transfer position; a primary fixing section that is disposed downstream of the transferring section, and is capable of bringing the transferred image into a fixing state where the image is fixed by pressurizing the image receiving medium, and into a non-fixing state; and a secondary fixing section that is disposed downstream of the primary fixing section, for fixing the transferred image by pressurizing the image receiving medium, wherein a conveying length of the image receiving medium from the transfer position to an image fixing position in the secondary fixing section is shorter than the length of the image receiving medium having a maximum length in the conveying direction, and a conveying length of the image receiving medium from the transfer position to a fixing position in the primary fixing section is shorter than the length of the image receiving medium having a minimum length in the conveying direction, and wherein when the image is formed on the image receiving medium of the maximum length, the primary fixing section is brought into the non-fixing state, and the transferring section transfers the image to such a position that the transfer is completed when the forward end of the image receiving medium reaches the secondary fixing section, and when the image is formed on the image receiving medium of the minimum length, the primary fixing section is brought into the fixing state, and the transfer section transfers the image to such a position that the transfer is completed when the forward end of the image receiving medium reaches the primary fixing section.
