摘要： An image forming apparatus includes a rotatable image bearer, a toner image forming device, an image reader, and a control unit. The toner image forming device forms a test toner image on the image bearer. The image reader reads the test toner image and a predetermined reference member. The control unit calculates an amount of toner contained in the test toner image based on image data from the test toner image. Based on image data from the reference member, the control unit selects a position of a pixel to be used for calculation of the amount of toner contained in the test toner image from pixels included in the image data from the reference member, to calculate the amount of toner contained in the test toner image from data of a pixel located at the position thus selected among pixels included in the image data from the test toner image.

摘要： An image forming apparatus includes an image bearer, an image forming device to form a toner image on the image bearer, a transfer device to transfer the toner image to a recording medium, a line sensor as an image density sensor to detect image density of the toner image, and a controller operatively connected to the image density sensor. The image density sensor is disposed so as to be shorter in a rotational direction of the image bearer than in a width direction of the image bearer perpendicular to the rotational direction of the image bearer. The controller forms a shading pattern image including a plurality of patches on the image bearer, and detects image density of the plurality of patches, so as to control image density. The shading pattern image is shorter in the rotational direction of the image bearer than in the width direction of the image bearer.

摘要： An image forming apparatus includes an image carrier, a transfer unit, and a control unit. The image carrier has a surface to bear a toner image thereon. The transfer unit has a transfer member to transfer the toner image onto a recording sheet conveyed in a conveyance direction for trailing-end borderless image formation and duplex image formation. The transfer unit is configured to form the toner image on the recording sheet without forming a margin at a trailing end of the recording sheet in the conveyance sheet in the trailing-end borderless image formation. The transfer unit is configured to form the toner image on front and back faces of the recording sheet in the duplex image formation. When a width of the toner image formed in a borderless image area of the recording sheet in the trailing-end borderless image formation is smaller in a direction perpendicular to the conveyance direction than a threshold value, the control unit permits the duplex image formation. When the width is the threshold value or greater, the control unit prohibits the duplex image formation.

摘要： A method and circuit for activating a liquid crystal matrix display panel in which during each selecting period, each liquid crystal cell pixel of the matrix, whether selected or unselected, receives either a primary selecting signal voltage or non-selecting signal voltage as well as an additional different secondary voltage to generate substantially homogeneous crosstalk noise over the entire display. The signal voltage applied to a pixel during a selecting period can vary between a primary selecting or non-selecting voltage applied for a first time interval followed by or preceded by a secondary voltage intermediate the selecting and non-selecting voltage applied for a second interval. Alternatively, the primary signal voltage applied to the pixel for a first time interval can be a selecting or non-selecting voltage and secondary voltage applied for a second time interval can be the other. In another embodiment of the invention, the relative duration of the primary and secondary voltages affects the darkness gradation of the display.
