Disclosed is an air cleaner having independent fluid paths and a home appliance having the air cleaner. The air cleaner includes a front panel having a plurality of air inlets formed thereon for air to flow in from outside of the case, first and second blower devices arranged inside the case to allow air to flow in through the plurality of air inlets, first and second filter units arranged to filter the air flowing in by the first and second blower devices, a first outlet located on the case to release the air, a second outlet formed at a different location from that of the first outlet, a first fluid path formed between one of the plurality of air inlets and the first outlet; and a second fluid path formed between another of the plurality of air inlets and the second outlet.

Air cleaner and home appliance having air processing unit

The disclosure relates to an air conditioner and a control method thereof, the air conditioner including: a housing including an inlet and an outlet through which air is introduced and discharged; a fan driver configured to drive air introduced through the inlet to be discharged through the outlet; a filter configured to filter the introduced air; a sensor configured to detect a foreign material in air; a storage configured to store information; and a processor configured to control the storage to store information about mass concentration of the foreign material in air detected by the sensor, and calculate a remaining life of the filter based on the information stored in the storage. Thus, the air conditioner can identify proper time to replace the filter by calculating the remaining life of the filter.

Air conditioner and method for controlling same

A display device including a display panel including a display area including a fingerprint sensing area and a plurality of pixels provided in the fingerprint sensing area; a sensor layer provided on one surface of the display panel overlapping the fingerprint sensing area, the sensor layer including a plurality of photo sensors; a panel driving circuit configured to output a data signal corresponding to image data to the display panel, corresponding to a first mode, and to output a driving signal to the display panel to allow the pixels to emit lights in a form corresponding to a predetermined light pattern, corresponding to a second mode; and a fingerprint detecting circuit configured to receive sensing signals from the photo sensors, corresponding to the second mode, the fingerprint detecting circuit detecting a fingerprint of a user, based on a sensing signal corresponding to the light pattern among the received sensing signals.

Display device and method of driving the display device

An image forming apparatus is disclosed. The image forming apparatus includes a photosensitive body, a magnetic roller disposed at a predetermined distance from the photosensitive body, and a donor roller disposed between the photosensitive body and the magnetic roller. The donor roller has a diameter larger than the closest distance between the photosensitive body and the magnetic roller. The image forming apparatus includes gap rings and pressing device to maintain desired gaps between the magnetic roller and the donor roller and between the donor roller and the photosensitive body.

Image forming apparatus including pressing unit to maintain gap between rollers

An electrophotographic image forming apparatus including first and second photosensitive bodies, first and second exposing units to form electrostatic latent images on the first and second photosensitive bodies respectively charged to a uniform electric potential, a first developing unit to develop an electrostatic latent image of the first photosensitive body by supplying a color toner to the electrostatic latent image of the first photosensitive body, and a second developing unit in which a transparent toner and a white toner charged to different polarities are contained and which develops a transparent toner image and a white toner image by respectively supplying the transparent toner and the white toner to an image portion and a non-image portion of an electrostatic latent image of the second photosensitive body.

Electrophotographic image forming apparatus having transparent toner and white toner

Provided are a multi-pass image forming apparatus and an image forming method using the same. The multi-pass image forming apparatus includes a plurality of developers for forming a plurality of electrostatic latent images using toners having different polarities and colors in one development process and for forming a multi-color image in at least two development processes; an exposure unit for forming the plurality of the electrostatic latent images on a photosensitive medium; and an intermediate transferring unit for having a toner images transferred thereon from the photosensitive medium that overlap to form the multi-color image, wherein the toner image may overlap another toner image on the intermediate transferring unit.

Multi-pass image forming apparatus and image forming method using the same for providing plural print modes with different numbers of passes depending on desired print speed and image quality

An image forming apparatus includes a developer storage tank which stores a developer therein and has a developer discharger to discharge the developer therethrough, a developer receiver which receives the developer, a delivery member which is connected with the developer discharger and delivers the developer to the developer receiver through a delivery path, and a vibrator which vibrates the delivery member.
