| 发明名称 | Image forming apparatus counting cumulative number of startups of fixing unit | ||
| 摘要 | An image forming apparatus that forms a toner image on a recording medium includes a fixing unit configured to fix the unfixed toner image on the recording medium while conveying the recording medium bearing the unfixed toner image at a nip portion. The fixing unit includes a fixing rotating member and a pressure member forming the nip portion with the fixing rotating member. The apparatus also includes: a counting portion configured to count the cumulative rotation time of the fixing rotating member and the cumulative number of startups of the fixing unit; and a notifying portion configured to performing notification of information about at least one of the lifetime expiration of the fixing unit and the necessity of replacing the fixing unit. The notifying portion performs the notification in accordance with the cumulative rotation time and the cumulative number of startups of the fixing unit. | ||

| 主权项 | 1. An image forming apparatus that forms a toner image on a recording medium, comprising: an image forming unit configured to form an unfixed toner image on the recording medium; a fixing unit configured to fix the unfixed toner image on the recording medium while conveying the recording medium bearing the unfixed toner image at a nip portion, the fixing unit including a fixing rotating member and a pressure member forming the nip portion with the fixing rotating member; a counting portion configured to count a cumulative rotation time of the fixing rotating member and a cumulative number of startups of said fixing unit; and a notifying portion configured to perform a notification of information about at least one of the expiration of the lifetime of the fixing unit and the necessity of replacing the fixing unit, wherein the cumulative rotation time is corrected such that, the larger the cumulative number of startups of said fixing unit, the longer the cumulative rotation time, and wherein the notifying portion performs the notification of the information in accordance with the cumulative rotation time that has been corrected. | ||
