摘要： A sheet member supply device (40) of an image forming apparatus (1) includes a sheet member stacking plate (43) in which sheet members (S) are stacked on the upper surface, a pickup roller (51) which makes contact with, from above, the uppermost layer of the sheet members (S) stacked on the sheet member stacking plate (43), a stacking plate displacement mechanism (44) which displaces the sheet member stacking plate (43) upward, a motive power transmission mechanism (60) which transmits motive power obtained from a drive source (45) to the stacking plate displacement mechanism (44) and a paradox planetary gear mechanism (65) which is provided in the motive power transmission mechanism (60). In this way, with a simple configuration, it is possible to reduce the unintentional downward displacement of the stacking plate.

摘要： A color correcting system mountable in an image forming apparatus comprises an imaging unit configured to perform image formation and a control unit configured to acquire a control parameter for use in image formation by the imaging unit and a status parameter indicating a status at the time of image formation. If a value for a color in an image formed by the imaging unit does not exceed a first threshold, and at least one member selected from the group consisting of adhering toner amount, gloss, line width, and line position for the image formed by the imaging unit does not exceed a second threshold, the control unit is configured to determine a control parameter on the basis of the acquired control parameter and the acquired status parameter, such that at least a color difference decreases.

摘要： A tension roller which is brought into contact with an inner circumferential surface of an endless belt and is rotated and which can be moved to a first position where the belt is in a relaxed state and a second position where the belt is in a tensioned state, a butting member which butts against the belt, a force application unit which applies, to the butting member, a force acting in a direction opposite to a rotation direction of the belt and a movement mechanism which moves the tension roller to the first position and the second position are provided. When the belt is rotated, the butting member is moved in the rotation direction of the belt by a friction force with the belt, and the movement mechanism moves the tension roller from the first position to the second position by the movement of the butting member in the rotation direction of the belt. When the rotation of the belt is stopped, the butting member is moved in the direction opposite to the rotation direction of the belt by the force applied by the force application unit, and the movement mechanism moves the tension roller from the second position to the first position by the movement of the butting member in the direction opposite to the rotation direction of the belt.

摘要： In an image forming apparatus, a sensor section which the printed sheets fed from an image forming section pass through or by in a first direction one by one, irradiates each of the passing printed sheets with light elongated in a second direction different, thereby sensing densities of the each of passing printed sheets, on a pixel basis. Further, a control section integrates densities of respectively corresponding line portions in respective non-image areas of sheets of the printed sheets, based on the densities obtained by the sensor section, each of the line portion extending substantially in the first direction and including pixels on substantially a same position in the second direction, thereby obtaining integrated density values, and predicts, based on the obtained integrated density values, that a noise will occur on a printed sheet to be made by the image forming section later on.

摘要： In an image forming apparatus, a sensor section includes a sheet path through which the sheet passes in a sheet feeding direction. In the sensor section, a light source unit emits light to an irradiation area set in the sheet path. Here, the light is elongated in a main-scanning direction and has quantities of light varying according to positions in the main-scanning direction and according to positions in a height direction perpendicular to a sheet feed surface. In addition, in the sensor section, a light-receiving section receives light diffused in a predetermined diffusing direction among the light emitted from the light source and then irradiated to the sheet passing in the sheet path and outputs information representing quantities of the received light. In the image forming apparatus, a control section extracts a parameter from the information and derives an amount of curl of the sheet.
