Abstract: A processor causes a printing portion to execute, when first conveying processing is executed, test print processing for executing processing of forming a plurality of test toner images on a sheet under a print condition that differs for each of the plurality of test toner images. The processor acquires a plurality of first sensing densities when the first conveying processing is executed. The processor causes the printing portion to execute the test print processing when second conveying processing is executed. The processor acquires a plurality of second sensing densities when the second conveying processing is executed. The processor compares the plurality of first sensing densities and the plurality of second sensing densities to adjust the print condition in the print processing when the second conveying processing is executed.

Abstract: An image forming apparatus includes a developing current detecting portion, a control portion, and a deviation detecting portion. The developing current detecting portion detects a developing current that flows between a developing device and a photoconductor drum during development of an electrostatic latent image. The control portion causes the exposure device to form electrostatic latent images of at least two patch images at different positions from each other and at different timings from each other in a main scanning direction. The deviation detecting portion detects deviation of one of the exposure device and the photoconductor drum with respect to the other based on a detection timing at which the developing current is detected during development of the electrostatic latent images of the at least two patch images.

Abstract: An image forming apparatus includes image forming portion, toner-disposal container, conveying portion, driving portion, load detection portion, image formation control portion, and image forming condition adjustment portion. The image forming condition adjustment portion corrects, when image forming condition does not conform to predetermined condition, the image forming condition. In a case where a drive load detected by the load detection portion becomes greater than first threshold value while the conveying portion is driven by the driving portion and the image forming operation is executed, the image formation control portion temporarily stops the image forming operation, and causes the image forming condition adjustment portion to check and correct the image forming condition. The image formation control portion restarts the image forming operation when, according to the image forming condition having been corrected, the drive load becomes less than second threshold value which is less than first threshold value.

Abstract: An image forming apparatus has a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a polishing member, a driving device, a voltage applying device, a torque detector, and a control portion. The photosensitive member has a photosensitive layer and a surface protection layer formed on the surface of the photosensitive layer. The polishing member has an elastic layer on its circumferential surface, and rotates with a linear velocity difference from that of the photosensitive member. The torque detector detects the torque of the driving device. The control portion estimates an attachment condition of discharge products to the surface of the photosensitive member based on the torque of the driving device detected by the torque detector. When the torque is equal to or higher than a predetermined value, the control portion performs an image degradation suppression process.

Abstract: An image forming apparatus (1) includes an image forming section (12), an intermediate transfer belt (125), a drive roller (125A), a secondary transfer roller (210), a brush section (80), a cleaning device (70), a power supply device (81), and a ground portion (82). The brush section (80) is disposed at a location downstream of the secondary transfer roller (210) in a direction of travel of the intermediate transfer belt (125) and facing the drive roller (125A) with the intermediate transfer belt (125) in between. A potential difference is applied between the brush section (80) and the secondary transfer roller (210) by the power supply device (81) and the ground portion (82), so that an electric current having the same polarity as a normal charge polarity flows from the brush section (80) through the drive roller (125A) to the secondary transfer roller (210).

Abstract: An image forming apparatus includes an image carrying member, an intermediate transfer belt, a primary transfer roller, a first belt support roller, a secondary transfer roller, a second belt support roller, a current feeder, a controller, a current sensor, and a rectifier. The current sensor has a lead member. The rectifier shuts off a current passing from the second belt support roller to the ground if the voltage on the second belt support roller is less than a predetermined reference voltage. The controller controls the output current such that the secondary transfer current has a current value resulting from subtracting a leak current from the output current and, when the lead member is in a conducting state, keeps the voltage on the second belt support roller less than the reference voltage.

Abstract: An image forming apparatus includes an image carrying member, an intermediate transfer belt, a primary transfer roller, a first belt support roller, a secondary transfer roller, a second belt support roller, a current output portion, a current sensing portion, and a control portion. The current output portion passes across the secondary transfer roller a secondary transfer current as part of an output current. The current output portion and the second belt support roller are electrically connected together. The current sensing portion senses a leakage current passing from the first belt support roller via the intermediate transfer belt to the second belt support roller. The control portion sets the output current such that the secondary transfer current has a value given by subtracting a leakage current from the output current and keeps the voltage on the second belt support roller between −50 V and 50 V, inclusive.
