20140168670 | IMAGE FORMING APPARATUS INCLUDING REMOVAL UNIT FOR REMOVING DEVELOPER - An image forming apparatus has a control unit configured to: after an image is formed in a color mode, if an integrated supply amount is larger than or equal to a reference supply amount, cause a supply image with a first amount of developer, otherwise, cause a supply image with a second amount of developer larger that the first amount; and, after an image is formed in the monochrome mode, cause a supply image with a third amount of developer smaller than the first amount, and, to make an interval between recording materials when the supply image with the third amount is formed shorter than an interval between recording materials when the supply image with the first amount or larger is formed. | 06-19-2014 |
20140169821 | IMAGE FORMING APPARATUS INCLUDING CLEANING UNIT FOR REMOVING DEVELOPING MATERIAL - An image forming apparatus includes a control unit, which is configured to, if a developing material image transferred to another member is formed on an image carrier, obtain a print ratio that is a ratio of the area of the formed developing material image with respect to the area of a developing material image capable of being formed on a recording material that is to be printed on, and a threshold value corresponding to a consumption amount of the developing material in a image forming unit and a number of sheets printed, and control an amount of developing material that is to be supplied to a cleaning unit in accordance with the print ratio and the threshold value. | 06-19-2014 |
20150093143 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image bearing member; an intermediary transfer member; a controller; and a cleaning unit. The cleaning unit includes a cleaning member for collecting a residual toner in contact with the intermediary transfer member, a charging member, which is provided downstream of the cleaning member with respect to a movement direction of the intermediary transfer member, for electrically charging the residual toner, and an accommodating member for accommodating the residual toner. The controller is capable of executing an operation in a discharging mode in which the toner is discharged from the charting member onto the intermediary transfer member. When the operation in the discharging mode is executed, the cleaning unit collects the toner, discharged from the charging member on the intermediary transfer member, by the cleaning member and then accommodates the collected toner in the accommodating member. | 04-02-2015 |

20110255118 | IMAGE READER APPARATUS AND METHOD OF DRIVING THE SAME - The present invention provides an image reader apparatus capable of obtaining an image having stable brightness while suppressing an increase of the cost of the apparatus. The image reader apparatus | 10-20-2011 |
20130176604 | IMAGE READING APPARATUS AND IMAGE READING METHOD - An image reading apparatus includes a touch panel that outputs a press position pressed by a finger as coordinate information in a sub-scanning direction, the finger being placed on the surface of the touch panel, a CCD that takes an image of the finger placed on the touch panel from the rear side of the touch panel in a main-scanning direction, and outputs an image signal, and a motor that moves the CCD in the sub-scanning direction so as to follow a rotational movement of the finger based on the movement amount detected by the movement detection unit. | 07-11-2013 |
20130300852 | IMAGE READING DEVICE - An image reading device includes: a diffuser for resting a finger on its upper surface and for diffusing light entering from its lower surface; a light source for irradiating the finger rested on the diffuser with light from the lower surface of the diffuser at a predetermined angle of irradiation; a mirror for receiving the light reflected from the finger on the diffuser which has been emitted from the light source; a CCD for, by receiving the light reflected with the mirror, capturing an image of the finger on the diffuser in a horizontal scanning direction from the lower surface of the diffuser, and then outputting an image signal; and a motor for moving, in a vertical scanning direction, a reading unit which includes at least the light source, the mirror, and the CCD. The upper surface of the diffuser on which the finger is rested is set to be a diffusion surface, and the lower surface of the diffuser through which the light from the light source enters is set as a non-diffusion surface. | 11-14-2013 |
