It is an object of the present invention to provide a simulation tool, which can overcome complications of examinations by simulations as described above and can provide a designer with easy examinations. A simulation based on a design parameter of a unit is implemented. Furthermore, a simulation result implemented by the control device is output on a display screen as a graph. Then, the unit design parameter is corrected in accordance with a correction in the graph displayed on the display screen. Thus, the simulation can be retried easily.

Information processor for supporting a sheet feeding machine design

The invention provides an aided design apparatus including a output element for outputting data of an attribute name associated with an attribute group of a part used for transporting a sheet along with three-dimensional shape data of the part. The invention further provides a related aided design method and a recording medium for recording a program for carrying out the method, wherein the data of parts used in a simulation for paper transportation can be easily exchanged.

Aided design apparatus, aided design method, and recording medium for recording program for carrying out the method

The image forming apparatus has exposing device, conveying device, and sheet detecting device for detecting the sheet conveyed by the conveying device, which is disposed between the transferring portion and the conveying device, and control device for judging whether or not it is possible to start exposure by the exposing device before the leading edge of the sheet conveyed by the conveying device reaches the sheet detecting device after the leading edge of the sheet passes through the conveying device and for controlling so that causing the sheet conveyed by the conveying device is stopped in front of the sheet detecting device until it is determined that it is possible to start exposure by the exposing device. In the image forming apparatus, the image forming apparatus starts to form a latent image by the exposing device based on the detection of the sheet by the sheet detecting device.

Image forming apparatus with conveyance and exposure control

An image forming apparatus comprising an image forming unit for forming a non-fixed toner image on a recording material, a heater for heating the non-fixed toner image, a back-up member for cooperating with the heater to form a nip therebetween, the back-up member pinching and conveying the recording material at the nip in such a manner that the non-fixed toner image is contacted with the heater so that the non-fixed toner image is fixed to the recording material by heat from the heater, and a cleaning member for cleaning the back-up member. The cleaning member is brought into a first and second cleaning mode in which an image forming operation is not effected and the back-up member is cleaned, the second cleaning mode having a cleaning time longer than a cleaning time of the first cleaning mode.

Image forming apparatus having fixing apparatus with cleaning device

An image bearing member, process device acting on the image bearing member, a first frame, a second frame lockable and separable with respect to the first frame, a locking body and a locking member lockable to the locking body, provided to separably interlock the first and second frames, and a recessed portion and a projection fittable into the recessed portion which are provided to separably interlock the first and second frames. With above construction it is possible to provide a process cartridge, an image forming system, and a method for assembling a cleaning device, which can be easily assembled and can sufficiently cope a large when the number of re-cycles.

Process cartridge mountable in an image forming system and a method for

A process cartridge includes a first frame in which a toner containing unit for containing toner used for a developing operation and a charger unit are mounted, and a second frame which can be engaged by and disengaged from the first frame, and in which an image bearing member, a developing unit and cleaning unit are mounted. With this arrangement, the assembling ability and disassembling ability are improved remarkably, and the process cartridge is suitable for the re-cycling to contribute to the protection of the earth-environment.

Process cartridge and image forming system on which process cartridge is

A process cartridge detachably mountable to a main assembly of an image forming apparatus, includes a plurality of process device including at least one member having an electrically conductive cylinder; a supporting frame for supporting as a unit the plural process devices; and an electrode, in the supporting frame, having a first portion electrically contactable to the main assembly and a second portion press-contacted to an end surface of the cylindrical member.

Process cartridge and image forming apparatus using same

An image fixing apparatus includes a heater; an endless film movable together with a supporting member for supporting a toner image, in which the toner image is heated by heat from the heater through the film; a driver for driving the film; and a limiter for limiting the lateral position of the film. At least a part of the endless film is limited by the limiter and is substantially tension-free when the film is driven.

Image fixing apparatus

A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.

Process cartridge detachably mountable to image forming apparatus

The present invention provides an apparatus for the handling of cleaned toner. The cleaning apparatus has a blade which removes residual toner from a photosensitive drum, a storage area partitioned into an upper and a lower section by a plate. In the preferred embodiment, a rotary device with paddles attached feeds toner to the rear of the lower section away from the cleaning blade and into the upper section. This insures the full use of the storage area. Plural rotary devices may be provided.

Cleaning apparatus with means to effectively use toner storage space

A reciprocating driving device is provided with a reciprocating moving member supported to be movable in a predetermined direction and the reverse direction. A first rack is provided on the reciprocating moving member, and a second rack is provided on the reciprocating moving member and arranged so as to face the first rack. A gear moves the reciprocating moving member in the predetermined direction or the reverse direction by rotating in a predetermined direction, selectively meshing with the first rack or the second rack.
