Abstract:
Disclosed is image forming apparatus, including a first roller and a second roller that conveys the recording sheet by sandwiching the recording sheet in a fixing process of an image forming; a pressing actuator that presses the first roller and the second roller against each other; an actuating motor that actuates the first roller; a brake that applies a brake force to the second roller; a rotation speed detector that detects a rotation speed of the second roller; and a hardware processor that judges a degradation of each surface roughness of the first roller and the second roller in accordance with the rotation speed of the second roller, which is detected when the first roller is actuated in a situation in which the first roller and the second roller are pressed against each other and when the brake applies a predetermined brake force to the second roller.

Claim (Index 8):
A lifetime judgment system, comprising:\n a server; and a plurality of the image forming apparatuses of  claim 1 , wherein the server collects information indicating a usage condition of each image forming apparatus and a result of judging the degradation, which is obtained when a fixing unit is replaced, from each of the image forming apparatuses, the server calculates a threshold value of a degradation progress of the surface roughness in each usage condition in accordance with the usage condition and the result of judging the degradation which are collected from each of the image forming apparatuses, the threshold value being used for judging whether a life of the fixing unit is exhausted, and the server judges a lifetime of the fixing unit in each image forming apparatus in accordance with the threshold value calculated in accordance with the usage condition of the image forming apparatus, or the server instructs the image forming apparatus to judge the lifetime of the fixing unit in accordance with the threshold value calculated in accordance with the usage condition of the image forming apparatus.
