    摘要: A developing device includes a plurality of conveyance passages, an opening portion, and a filter. Developer is conveyed in the plurality of conveyance passages in a longitudinal direction of the developing device. The opening portion is disposed in one conveyance passage of the plurality of conveyance passages and communicates with an outside of the developing device. The filter is fitted in the opening portion and has both a collecting ability to collect the developer and a ventilation ability to ventilate the one conveyance passage to the outside of the developing device. The collecting ability of the filter is higher in a high-bulk portion in which bulk of the developer increases in the one conveyance passage than in a low-bulk portion in which the bulk of the developer decreases in the one conveyance passage. The ventilation ability of the filter is lower in the high-bulk portion than in the low-bulk portion.

    摘要: An image forming apparatus includes a fixing device, a temperature detector, and processing circuitry. The fixing device fixes a toner image on a surface of a sheet by heating of a heater. The temperature detector detects an internal temperature of the image forming apparatus. The processing circuitry switches a continuous print mode to an intermittent print mode when the internal temperature is equal to or higher than a first execution temperature during the continuous print mode. The processing circuitry cancels the intermittent print mode and switches to the continuous print mode when the internal temperature is equal to or lower than a first cancellation temperature. The processing circuitry causes the heater to stop heating the fixing device in the intermittent print mode when the internal temperature is higher than the first cancellation temperature even after a predetermined time has elapsed since a start of the intermittent print mode.

    摘要: The image forming apparatus includes a process unit, a latent image writer, a power source, and a controller. The process unit is detachably attachable relative to the image forming apparatus and includes, as a single integrated unit, a latent image bearing member to bear a latent image on a surface thereof, a charging device to charge the surface of the latent image bearing member, and a development device to develop the latent image with toner. The controller causes the power source to output a charging bias at a predetermined target level supplied to the charging device. The process unit includes a first storage device to store correction information for calculating the predetermined target level of the charging bias in accordance with a combination of the latent image bearing member and the charging device. The controller corrects the predetermined target level based on the correction information in the first storage device.

    摘要: An image forming apparatus capable of executing continuous image forming operation forming images on more than one page includes a temperature detector that detects internal or surrounding temperature of a developing device correspondingly changing to temperature of a developer bearer. A temperature information acquiring device acquires information of ambient temperature outside of the image forming apparatus. A controller switches a current operation mode to an intermittent image forming operation mode intermittently including a braking time period not to allow image formation and cancels the intermittent image forming operation mode in accordance with detection result of the temperature detector. The intermittent image forming operation mode allowed to continuously form images only on a prescribed limited number of sheets. The controller varies the braking time period in accordance with the ambient temperature detected by the temperature information acquiring device.

    摘要: An apparatus calculates a delay time of nets within a circuit included in design data by a processing unit. The processing unit performs a process that includes selecting a first calculation to calculate the delay time of a net when the net satisfies a first condition, when the first calculation is not selected by the selecting, selecting the first or second calculation to calculate the delay time of the net, depending on whether the net satisfies a second condition, and calculating the delay time of the net by the first or second calculation selected by the selecting.
