摘要： An image forming apparatus includes a latent image bearing member, a charging unit, a charging power source, a latent image writing unit, a development unit, a transfer unit, a toner detector, and a controller. The controller causes a background fog pattern to be formed on a surface of the latent image bearing member. In addition to the background fog pattern, the controller causes a latent image to be developed to form a toner image used for position identification on the surface of the latent image bearing member. The controller identifies a time when the toner image used for position identification has entered a detection range of the toner detector based on a change in outputs of the toner detector to determine a time when each of sections of the background fog pattern enters the detection range based on the identified time.

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： 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.
