摘要： To provide an image formation device (1) in which life determination is performed according to a relationship between a development unit (10) and a photoreceptor (7) or in which life management is performed based on a parameter directly linked to the film thickness of the photoreceptor (7), so that life expiration can be determined after the potential life of a consumable has been used up.
The image formation device (1) including a photoreceptor (7) configured to carry a toner image and a replaceable development unit (10) configured to form the toner image on a surface of the photoreceptor (7), includes: a development bias application section (18) configured to apply a development bias to between the photoreceptor (7) and the developer (10); a stabilization control section configured to perform image stabilization control of determining a development bias value to be used in future by changing the development bias while measuring a density of the toner image formed by the developer (10), thereby obtaining the toner image with a target density; and a life determination section configured to determine expiration of use of the development unit (10) when the development bias value determined by the stabilization control falls outside a preset acceptable range.

摘要： A pressure device applies pressure to a sheet medium on part of a surface of which an image bearer is formed. The pressure device includes: a driving unit that changes a distance between a first pressing unit and a second pressing unit; a control unit that controls the driving unit such that the distance between the first pressing unit and the second pressing unit becomes a set target value; and a target setting unit that sets the target value to a first distance that is larger than a thickness of the sheet medium when the sheet medium is not present between the first pressing unit and the second pressing unit, and sets the target value to a second distance for applying a target pressure to the sheet medium when the sheet medium and the image bearer are present between the first pressing unit and the second pressing unit.

摘要： In a case where conveyance abnormality of a sheet has occurred on a conveyance passage in course of execution of a print job which uses sheets included in a sheet set including a plurality of sheets with sequentiality stored in a first sheet feed tray (161) and discharges a sheet having been subjected to image formation to a first discharge section of the plurality of discharge sections (290, 390, 491, 492) conveyance of a causal sheet having caused the conveyance abnormality is stopped, and sheets having been being conveyed on the conveyance passage on an upstream side than the causal sheet are discharged to other discharge section other than the first discharge section. Thereafter, continuously, sheets located before a sheet to be fed first at a time of performing recovery printing after elimination of conveyance abnormality, are fed from the first sheet feed tray, and discharged the sheets to the other discharge section.
摘要翻译：在执行利用第一供纸托盘（161）中存储的顺序性地使用包括多张纸张的纸张组中包含的纸张的打印作业执行过程中，在传送通道上发生纸张传送异常的情况下，已经对已经导致传送异常的因果纸张的多个排纸部分（290,390,491,492）中的第一排纸部分进行图像形成的纸张被停止，并且已经在传送装置上传送的纸张在因果用纸上游侧的通路被排出到第一排出部以外的其他排出部。之后，在排除传送异常之后，在执行恢复打印时首先进给的片材之前的片材连续地从第一片材馈送盘馈送，并且将片材排出到另一个排出部分。
