摘要： In a charging device having saw-tooth electrodes for generating corona discharges, an amount of dust, toner, or paper dust attached to the tip end portions of saw-tooth electrodes is reduced. First to third pairs of saw-tooth electrode plates are disposed in a side-by-side fashion along the periphery of a photosensitive drum in which the first pair is disposed at an upstream side with respect to a direction in which the photosensitive drum rotates, the third pair at a downstream side, and the second pair at a central portion between the remaining two. A current flowing per a unit length of the second pair is set to 1.3 to 3 times as much as a current flowing per a unit length of each of the first and third pairs. The currents flowing per a unit length of the first and third pairs are set to be equal to each other.

摘要： A transport roll 1 consists of a metal roll 3 of 40 mm in diameter covered with a conductive PFA tube 2 of 10.sup.10 .OMEGA.cm in volume resistivity and 200 .mu.m in thickness. A DC voltage source 4 is connected to the metal roll. A sheet of paper 5 bearing toner images 6 and 7 on both sides thereof receives a drive force from a paper drive roll, and turns with the movement of the paper. The DC voltage source produces voltage VB1 of the same polarity as the charging polarity (positive) of the toner image 6 being in contact with the transport roll. The voltage VB1 is optimumly controlled so as to prevent the transport roll from being soiled with toner.

摘要： An ink discharge device is provided including an ink, an ink discharge head, and a circulator. The ink discharge head includes a nozzle, an individual liquid chamber communicated with the nozzle, a flow-in channel, and a flow-out channel. The circulator circulates the ink by letting the ink flow into the individual liquid chamber via the flow-in channel and flow out from the individual liquid chamber via the flow-out channel. A flow rate of the circulated ink is 0.10 to 1.50 times a maximum dischargeable rate of the ink discharge head. A dynamic surface tension A of the ink at 25° C. is 34.0 mN/m or less when measured by a maximum bubble pressure method at a surface lifetime of 15 msec, and the dynamic surface tension A and a static surface tension B of the ink at 25° C. satisfy the following relation: 10.0(%)≤[(A−B)/(A+B)]×100≤19.0(%).

摘要： An image production apparatus includes at least one image production unit having a latent image forming device for forming a latent image on an image carrying member and a developing device for attaching toner to the latent image formed by the latent image forming device. A toner image formed by the image production unit is transferred to a transfer medium to produce an image. The image production apparatus further includes a periodicity giving device for giving periodicity to movement in a main scanning direction of the image carrying member or transfer medium. According to this periodicity, the movement time from an image forming position to a transfer position, or the movement time of a transfer medium between adjacent transfer positions is set equal to an integral multiple of the period.

摘要： A developing device to develop a latent image on a rotatable image bearer includes an upstream developing roller disposed opposite the image bearer at a first developing position, and a downstream developing roller disposed adjacent to and downstream from the upstream developing roller in a direction of rotation of the image bearer, disposed opposite the image bearer at a second developing position. Each of the upstream developing roller and the downstream developing roller has a most approachable surface that approaches closest to the image bearer and a most withdrawn surface that withdraws farthest from the image bearer. In a state in which a reference surface point of the image bearer is disposed opposite the most approachable surface of the upstream developing roller at the first developing position, the reference surface point opposes the most withdrawn surface of the downstream developing roller at the second developing position.
