Patent ID: 8121508

Claim:
An image forming apparatus comprising: an image former operable to, upon receiving a first instruction, feed a sheet and perform an image forming operation so as to form an image on the fed sheet; a fixing part operable to (i) secure a fixing nip by bringing an outer circumferential surface of a first rotating body and an outer circumferential surface of a second rotating body into contact with each other, (ii) upon receiving a second instruction, heat at least one of the first and second rotating bodies until a temperature of the first and second rotating bodies reaches a target temperature required for image-fixing, and (iii) thermally fix the image onto the sheet passing through the fixing nip; and a determiner operable to determine an output timing of the first instruction and an output timing of the second instruction such that a timing at which a leading end, in a sheet convey direction, of the image formed on the sheet reaches the fixing nip and a timing at which the temperature of the first and second rotating bodies reaches the target temperature match each other.
