摘要:
In an image forming apparatus including an image forming unit that forms an image on a recording medium conveyed from a sheet feeding unit to obtain an image with photographic quality, at least a part of the recording medium has a transparent portion. When an image obtained by reversing an original image is transferred onto the transparent part, sheet-delivery rollers are operable in a direction in which a pressure onto the recording medium is reduced immediately after fixing of the image.

An upper rail is slidably provided on a lower rail fixed to a floor of a vehicle body. The front end of a seat cushion is connected with the front end of the upper rail such that the seat cushion is pivotal forwardly for inversion. The lower end of a seat back is connected with the rear end of the upper rail through a reclining mechanism such that the seat back is tiltable. The seat back is tilted pivotally forwardly into the space from which the seat cushion has been pivotally moved for inversion. A baggage-placing surface is formed of a bottom plate of the inverted seat cushion and a rear plate of the seat back tilted pivotally forwardly.

An apparatus having a plurality of replaceable parts. Replaceable parts to which the same life is assigned beforehand are replaced at the same time by hand or by use of a jig. Lives which are integral multiples of the shortest life which one of the replaceable parts has each is assigned to respective one of the other replaceable parts. Hence, when the life of a certain part has expired, the part having the shortest life is automatically replaced together with the part whose life has expired. The replaceable parts each is mounted on and locked to the apparatus and, when the life thereof has expired, unlocked from the apparatus. The expiration of the life is detected either electrically or mechanically, and the parts reached the end of the life is indicated. Before the life of a replaceable part expires, a spare part for replacing it is prepared by detecting that the life is about to expire. The deterioration of a part having a comparatively long life is measured to correct the time for replacing it.

A pair of registration rollers align a leading edge of a recording medium having a transparent section and a non-transparent section. A boundary sensor detects a boundary between the transparent section and the non-transparent section. The boundary sensor is provided on a downstream side of a direction of conveying the recording medium by the registration rollers.

In an image forming system, a lifetime management device calculates remaining lifetime of process units, a transfer unit, a secondary transfer unit, a belt cleaning unit and a fixing unit mounted on an image forming apparatus based on an operation amount thereof and a predetermined lifetime index. Based on the remaining lifetime and a predetermined replacement index, the lifetime management device determines whether any unit needs to be replaced, and, if any, transmits a replacement request signal to an external information processor together with a signal indicating remaining lifetime of other units via a communication line.

Process units, a transfer unit, a belt cleaning unit, a secondary transfer unit and a fixing unit each include a storage unit that stores therein information on the operation amount thereof measured by a controller as operation record with respect to each unit. The controller updates the information stored in the storage unit after each time the controller measures the operation amount. The controller calculates remaining lifetime of the units based on the operation amount and a predetermined lifetime index.

A recording medium is conveyed through a conveyer path. A recording-medium selecting unit selects either one of a non-transparent recording medium and a transparent recording medium, and conveys a selected recording medium to the conveyer path. An image selecting unit selects an image to be formed on the recording medium from among an original image and a reversed image obtained by reversing the original image. A control unit controls, based on a control signal, the recording-medium selecting unit and the image selecting unit.

A control unit controls a device that executes an image forming process, compares changes of each toner adhesion amount in an image-density-detection pattern image when a developing-bias control condition is changed, with respect to a toner adhesion amount in an image-density-detection pattern image in a normal status, performs a malfunction-occurrence prediction process according to the degree of each change of the densities, and displays the result.

An image forming system includes an image forming apparatus that includes process units for different colors and a lifetime management device that manages lifetime information on each unit of the image forming apparatus. The lifetime management device counts the number of prints produced by the image forming apparatus with respect to each of photoconductor units and developing units in the process units, and measures an operation amount unique to the respective units. Based on the number of prints, service life of each unit and operation amount, the lifetime management device calculates the remaining lifetime of each unit.
