| 20090060548 | Image Forming Apparatus - An image forming apparatus is configured to form a developer image on a recording sheet. The image forming apparatus includes a fixing unit including a pressure roller and a heat roller, an ejection roller configured to cause the recording sheet from the fixing unit to be ejected from the image forming apparatus, and a power transmission member configured to transmit power from the heat roller to cause the ejection roller to rotate. The pressure roller is configured to rotate in response to power and configured to cause the heat roller to be rotated. | 03-05-2009 |
| 20090245901 | Thermal Fixing Unit Having Pivotally Movable Pressure Pad and Image Forming Device Provided with the Same - There is provided a thermal fixing unit that fixes a toner image on a printing medium, the fixing unit including a heat member, a pressure pad, a movable supporting assembly, and an urging member. The heat member is in contact with the printing medium, being positionally fixed and defining an axis. The pressure pad is disposed in opposition to the heat member for nipping the printing medium in cooperation with the heat member. The supporting assembly pivotably movably supports the pressure pad. The urging member biases the supporting assembly to urge the pressure pad toward the heat member for providing pressure contact between the heat member and the pressure pad. | 10-01-2009 |
| 20100014887 | Image Forming Apparatus - An image forming apparatus includes: upper frames opposed to each other across an image forming unit; a scanner supporting member that couples the upper frames and supports the scanner unit; and a frame coupling member that couples the upper frames on an opposite side of the scanner supporting member across the photoconductor unit; lower frames, each of which has an upper surface including a plurality of lower supporting portions each contacting a lower end of a respective one of the upper frames, and a lower surface including a bottom supported portion opposed to a placing surface. A stiffness of each of the upper frames in a substantially planar direction along the vertical direction is greater than a stiffness of each of the lower frames along the vertical direction between the lower supporting portions and the bottom supported portion. | 01-21-2010 |
| 20100215419 | Image Forming Device Capable of Reliably Transmitting Driving Force to Belt Unit - An image forming device includes a main body having a metal main frame, first and second resin frames attached to the main frame, a conveying section attached to the first resin frame and made of third resin, an input section provided to the conveying section, and an output section supported to the second resin frame and liked to the input section. The conveying section conveys a recording medium upon receiving driving force through the input section and the output section. Both the first and second resin frames have a higher liner expansion coefficient than the main frame, and a linear expansion coefficient of the third resin is higher than that of the main frame and lower than that of the first and second resin frames. | 08-26-2010 |
| 20100239306 | IMAGE FORMING APPARATUS - An image forming apparatus including: a frame member including a first electrode; a replacement unit including a second electrode that electrically contacts the first electrode, wherein the replacement unit is movable relative to the frame member along with a moving direction, the moving direction includes a first direction and second direction that intersects the first direction, wherein one of the first electrode and the second electrode, which is formed by a wire, and which includes a contact portion, wherein the contact portion, which is bent along a intersection plane, and which is movable in a third direction that is perpendicular to the first direction and the second direction, and wherein a direction of contact portion is set so that the intersection plane intersects with a first plane and a second plane at angles smaller than an intersection angle formed by the intersection of the first plane and the second plane. | 09-23-2010 |
| 20100329757 | Image Forming Apparatus - An electrophotographic image forming apparatus may include a main body including a reference protrusion having a reference surface on one side and a pressing member on the other side, and a photosensitive member unit configured to move between an operational position and an outer position. The photosensitive member unit stops at a particular position located between the outer position and the operational position. The reference surface of the main body may contact the photosensitive member unit located in the operational position. The pressing device of the main body may be configured to press the photosensitive member unit toward the reference surface when the photosensitive member unit is located in the particular position and in the operational position. | 12-30-2010 |
| 20110065336 | IMAGE FORMING APPARATUS AND ELECTRODE MEMBER FOR THE SAME - An image forming apparatus includes: a first electrode including a spring portion extending in an axial direction and an annular contact portion extending from a first side in the axial direction; a first frame including a through hole, through which the annular contact portion protrudes; and a second frame, which is relatively movable to the first frame along an elongated direction of the annular contact portion at a further extension of the first side in the axial direction, and which includes a second electrode electrically connectable with the annular contact portion. A diameter of the annular contact portion is larger than that of the spring portion. The first frame includes a lock portion that locks the annular contact portion to place a center of the annular contact portion on a second side, which is opposite to the first side, in the axial direction from an end of the through hole. | 03-17-2011 |
| 20110102983 | IMAGE FORMING APPARATUS - An image forming apparatus includes a first right frame, a first left frame facing the first right frame, a second right frame positioned below the first right frame, a second left frame facing the second right frame and positioned below the second right frame. The image forming apparatus further includes an image forming unit positioned between the first right frame and the first left frame. The image forming apparatus still further includes a frame connecting unit configured to connect the first right frame, the first left frame, the second right frame and the second left frame. The first right frame and the second right frame are relatively slidable in an up-down direction, and the first left frame and the second left frame are relatively slidable in the up-down direction. | 05-05-2011 |
