    Abstract: There is a need to provide an image generator and an image generation method capable of avoiding wasting a normal printed matter if any in sheets of paper output after an occurrence of waste paper. When paper contains an abnormal image, the paper is detected as waste paper based on a read result from an image read sensor. Detection of the waste paper allows an image generator to perform reprint from a print job for the waste paper. Normal-image paper may be contained in sheets of paper output between detection of the waste paper and the reprint to be performed. In this case, the normal-image paper is used as a normal printed matter and is avoided from being consumed wastefully.

    Abstract: A cleaning apparatus and a fixing apparatus include a cleaning web configured to remove toner adhering to a rotation member, the cleaning web including a recessed portion in at least a part thereof, and a displacement mechanism configured to situate a relative position between the rotation member and a pressure member configured to press the cleaning web toward the rotation member at a first position where the cleaning web is pressed toward the rotation member by the pressure member and at a second position where the rotation member and the pressure member are farther from each other than at the first position. The displacement mechanism situates the relative position at the second position based on an output of a detection position configured to detect a position of the recessed portion, so that a rear end of the recessed portion is not pressed toward the rotation member by the pressure member.

    Abstract: A transfer belt transfers a toner image carried on a first main surface to a recording medium. When the transfer belt is pressed by using a lower block provided with a hole and an upper block with pressurization force increased at a prescribed rate and thereafter kept constant, E [-] and t0 are curve-fitted to a function E=α×exp(−t0/τ) defined by a time constant τ [s] with respect to an amount of displacement of the transfer belt and a constant α [-], where E [-] is calculated as (a−b)/b, a [μm] represents a maximum value of an amount of displacement of a measurement region, b [μm] represents an amount of displacement of the measurement region after converged, and t0 [s] represents a time period from start of pressurization until the maximum pressurization force, and time constant τ satisfies a condition of 0.015≦τ≦0.1.

    Abstract: An image reading device includes an image reading unit, a conductive member, a switching portion, and a switching control portion. The image reading unit includes a light emitting portion and a light receiving portion. The light emitting portion irradiates light on a document sheet that is conveyed while in contact with an upper surface of a plate-like contact member. The light receiving portion outputs image data corresponding to light reflected from the document sheet. The conductive member is provided on a lower surface of the contact member. The switching portion is switched between an on-state and an off-state so as to select between a state where the conductive member is grounded or a state where the conductive member is not grounded. The switching control portion controls switching of the switching portion.
