    摘要： An image forming apparatus includes multiple image forming units each including a latent image bearer and a developing device, a transfer device to transfer toner images from the latent image bearers onto a surface of endless rotary member, a cleaner to clean the surface of the endless rotary member, and a control unit to execute a forcible toner consumption process to forcibly consume degraded toner stored in applicable one or more developing devices. The forcible toner consumption process includes a step of forming a toner image formed for forced consumption in a non-image region of the latent image bearer with an amount of toner corresponding to a difference between an image area ratio of a developed image and a prescribed threshold when the image area ratio of the developed image is lower than the prescribed threshold.

    摘要： 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.

    摘要： In an electrophotographic recording apparatus of the type using a single-ingredient type developer, i.e., toner, a developing device has a developing roller for conveying the toner deposited thereon, and an intermediate roller for conveying the toner transferred theretofrom the developing roller and depositing it on a latent image electrostatically formed on an image carrier to thereby produce a corresponding toner image. During the development of an area of the image carrier other than a latent image area, a bias assigned to the developing roller is switched over to thereby form an electric field different in direction from an electric field assigned to the formation of the toner image between the two rollers. Further, before the rotation of the image carrier is stopped, the bias assigned to the developing roller is again switched in order to form the electric field for the formation of the toner image between the rollers. As a result, a toner layer is formed on the intermediate roller. Subsequently, the rotation of the image carrier is stopped. The device obviates defective images ascribable to the adhesion of the image carrier and intermediate roller while eliminating background contamination and wasteful toner consumption.

    摘要： In an image forming apparatus, a developing device has a first developer carrier for depositing a developer thereon, a regulating member for regulating the amount of the developer deposited on the first developer carrier, and a second developer carrier having an elastic surface, and contacting the first developer carrier while biting into it by a predetermined amount. The developer is provided with a preselected degree of fluidity. Hence, even when the same portion of the surface of the second developer carrier runs a plurality of times past a position where the two developer carriers contact each other without any developer being fed from the second developer carrier to an image carrier, the first developer carrier can surely strip the developer from the second developer carrier. As a result, a developer on which a predetermined amount of charge is deposited is transferred from the first developer carrier to the second developer carrier. This successfully protects images from defects. Particularly, when the developer has a zinc stearate content of greater than 0.1 wt %, it is possible to prevent the developer from melting and adhering to a member which regulates the developer.

    摘要： 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.
