Abstract: The image forming apparatus includes a sheet conveyance part, an image forming part, and a sheet reading unit. The sheet reading unit includes a line sensor. The line sensor includes split line sensors. The line sensor reads a conveyed sheet. The line sensor includes a plurality of split line sensors. The split line sensors are placed at non-stretching positions, respectively. Each non-stretching position is such a position that as in the main scanning direction, a main-scanning-direction distance from a gap between one split line sensor and another split line sensor to an ideal edge position of every usable regular size exceeds a permissible value.

Abstract: An image forming apparatus includes a line sensor capable of reading a sheet being conveyed. A signal processing circuit generates, based on respective analog picture signals of pixels and in order of sequence of the pixels, detection signals each indicating whether or not a reflecting object has been read. A first counting circuit measures a duration time which is a time during which the detection signals maintain a level indicating that the reflecting object has been read. When the duration time reaches or exceeds a first specified time, the first counting circuit changes a level of a first detection result signal to a level indicating necessity of cleaning. A unit control circuit determines, based on the level of the first detection result signal, whether or not cleaning is necessary.

Abstract: An image forming apparatus is capable of correcting a lateral deviation and/or a skew of a sheet. A pair of conveying rollers convey the sheet to a transfer position of an image. An image sensor reads the sheet on an upstream side of the transfer position in a sheet conveying direction. A control device senses a foreign substance on a reading surface of the image sensor as well as calculate a lateral deviation amount and/or a skew amount of the sheet based on an output signal of the image sensor.

Abstract: A belt drive device includes a first pulley, a second pulley, a first bulging portion, a belt, and a pressing portion. The first bulging portion is formed along an outer periphery of the second pulley to bulge outward in a radial direction of the second pulley at a center of the second pulley in an axial direction of the second pulley. The belt is stretched between the first pulley and the first bulging portion. The pressing portion presses an outer peripheral surface of the belt at a center of the belt in a width direction of the belt.

Abstract: A toner container is removably mounted in a housing of an image forming apparatus. The toner container contains a toner and has a stirring member for stirring the toner. An electric motor drives the stirring member. A storage device stores a required load value set for the toner container. A load detecting section includes an electric current sensor that measures a drive electric current of the electric motor. The load detecting section detects an actual load value of the electric motor in driving of the stirring member based on the drive electric current measured. A determination section compares the actual load value detected by the load detecting section with the required load value stored in the storage device and determines whether or not the actual load value coincides with the required load value to determine whether or not the toner container mounted in the housing is a genuine product.

Abstract: An overcurrent protection device satisfactorily detects overcurrent without adding complicated component or occupying large space. Penetration member penetrates board face A having a first wiring circuit and face B with a second one, transmitting heat from face A to B. Connection/disconnection part is inserted into first wiring circuit, switching current to heat generation part for generating heat with current, formed in portion of first circuit, continued with one end of penetration member. Temperature detection member disposed near or abutted against other end of penetration member on face B detects transmitted heat, outputting signal. Control part controls connection/disconnection part on signal. Heat generation part is narrower than width w1 not generating heat in steady state, having width w2 to raise temperature upon overcurrent, and being sandwiched between patterns with width w1. Control part turns off current with heat generation part temperature raised to or above prescribed threshold.
