A disclosed fixing device includes a first roller, a second roller, a lubricant application unit applying lubricant to a surface of the first roller, a lubricant control blade being in contact with and separated from the surface of the first roller, so that the recording medium on which the image is formed is sandwiched and fed between the first roller and the second roller so as to fix the image onto the recording medium, a contact angle θ of the lubricant control blade relative to the first roller is in a range between 35 degrees and 43 degrees, and a linear pressure F applied from the lubricant control blade to the first roller is in a range from 0.35 N/cm to 0.5 N/cm.

A printing system including: a first printer that forms an image on continuous-form printing paper, and includes a pre-heating unit that preliminarily heats the continuous-form printing paper prior to fixation and a fixing unit that performs the fixation; and a second printer that forms an image on the continuous-form printing paper fed from the first printer. The second printer includes a jam detecting unit that detects, at a detection position upstream of a position where the second printer forms the image on the continuous-form printing paper, and a control unit that controls the jam detecting unit such that the jam detection is not performed for a period of time, over which a deformed portion of the continuous-form printing paper which has been at rest at the pre-heating unit of the first printer passes through the detection position of the jam detecting unit.

A fixing device includes: a fixing member that fixes a toner image onto a recording medium; a pressing member that presses the recording medium against the fixing member; an oiling unit that applies release oil onto a surface of the fixing member to clean the surface; a removing member that is arranged between an downstream side of the oiling unit and an upstream side of the pressing member in a rotating direction of the fixing member and movable between an in-contact state where the removing member is in contact with the surface of the fixing member and an out-of-contact state where the removing member is out of contact with the surface; a drive unit that drives the removing member; and an oiling control unit that, when starting earliest fixing, controls the drive unit to gradually move the removing member from the in-contact state into the out-of-contact state.
