摘要： An image forming section includes a bearing member configured to bear an image, and a plurality of light-emitting-element groups each having a plurality of light emitting elements arranged linearly in an arrangement direction. The image forming section forms an image on the bearing member by using the light-emitting-element groups to transfer the image on a sheet. The reader reads an image on a sheet. When executed by the processor, the instructions cause the processor to perform: a pattern reading process of controlling the reader to read a pattern image, the pattern image being an image for detecting density deviation and formed on the sheet by using the light-emitting-element groups; and a calculating process of calculating an amount of density deviation of each of the light-emitting-element groups based on a reading result by the pattern reading process. Each light-emitting-element group is a unit of calculation of the amount of density deviation.

摘要： In an image forming apparatus, a control device obtains an amount of toner in a first area and an amount of toner in a second area. The first area is defined on a conveying member that is in contact with a photosensitive member. The transfer of toner is assured in the first area of the conveying member, but is not assured in the second area. The control device determines a toner condition based on a difference in the amount of toner between the first area and the second area. When the difference in the amount of toner is larger, the control device determines that the toner is in a deteriorated condition. When the difference in the amount of toner is smaller, the control device determines that the toner is not in the deteriorated condition.

摘要： An image-forming device includes an image bearing member, a data providing unit, an image-forming unit, a detecting unit, a first calculating unit, a determining unit, and a second calculating unit. The image bearing member has a surface moving at a surface speed. The data providing unit provides pattern data indicative of a target test pattern to be formed on a target position of the surface in response to a test instruction. The image-forming unit forms an actual test pattern on an actual position of the surface in accordance with the pattern data provided from the data providing unit, and configure to form an image in response to an image-forming instruction. The detecting unit detects the actual position. The first calculating unit calculates a deviation of the actual position from the target position. The determining unit performs a first determination of whether the surface speed when the data providing unit receives the test instruction is stable or unstable. The second calculating unit calculates a correction amount based on the deviation and the first determination. The image-forming unit forms, in response to the image-forming instruction, an image on a position of the surface. The position is corrected based on the correction amount.

摘要： In an image forming apparatus, developer remaining on a photosensitive member as transfer residual developer is caught temporarily by a catching portion. In a collecting process, the transfer residual developer caught by the catching portion is returned to the photosensitive member, the transfer residual developer then is transferred onto a conveyor member, and the transfer residual developer is collected by a collecting portion. In the collecting process, the presence or absence or an amount of the transfer residual developer transferred onto the conveyor member is measured.

摘要： A controlling section controls an image forming section to form a calibration pattern on an object. The calibration pattern includes a plurality of marks in first and second groups. The marks in the second group are formed at a different position in the second direction from the marks in the first group. The marks in each of the first and second groups are arranged in the first direction over a predetermined range on the object. Each mark has shape and color. The detecting section detects the calibration pattern formed on the object, thereby obtaining detection results. The correcting section corrects, based on the detection results, an image forming position at which the image forming section forms an image. The marks belonging to different groups and having a same color are formed at different positions with respect to the first direction in at least part of the predetermined range.
