摘要： In an image forming apparatus that uses toners of a plurality of different colors, amorphous toner is used during image forming with a first color. Then, a controller, by using a toner remaining-removing switching device, causes toner scraped off from an image carrier by a blade during cleaning to remain at a predetermined region near the blade. Spherical toner is used during image forming with a second color and thereafter. The controller switches the toner remaining-removing switching device during any one of processes starting from the process of the second color until the end of image formation to remove toner remaining at the predetermined region, and the toner subsequently scraped off, from the image carrier.

摘要： A low cost image forming apparatus can be provided in which the amount of remaining toner of each color in each development apparatus can be detected by a single detection sensor device and at the same time whether the development apparatus is attached to or detached from the image forming apparatus can be discerned by the detection sensor device. The image forming apparatus includes development apparatuses for each color for developing an electrostatic latent image and supply of the developer is controlled based on the detected amount of toner in each of the development apparatuses. The detection sensor device includes a light emitting member and a light receiving member which receives the light emitted from the light emitting member and output a detection signal in accordance with the intensity of received light. Each of the development apparatuses has a light path member or members and the light emitted from the light emitting member advances through the light path member or members in which the light is formed into a light different in pattern with respect to each development apparatus. Therefore, the development apparatus brought to the developing position can be discerned and the amount of toner in the development apparatus can be determined based on the detection signal, thereby supply of developer to the development apparatus is controlled.

摘要： In image formation of a black-line image, the image is developed with black toner, and in addition parts of the black-line image corresponding to an intersection between at least two black lines and a middle portion of a black line are developed with toner of at least one of cyan, yellow, and magenta colors overlaid. This makes it possible to prevent central voids in a black-line image. In a black-line image transferred onto a transfer medium by this full-color image forming apparatus, not only are central voids eliminated, but degradation of image quality is also prevented.

摘要： An image forming apparatus includes: a development unit that develops an electrostatic latent image on an image bearing member and is demountable from a main body of the apparatus; a developer bearing member that is provided in the development unit and supplies a developer it bears to the image bearing member; a motor that drives the developer bearing member to rotate; and a control portion that allows the motor to rotate in a first rotation direction and in a second rotation direction reverse to the first rotation direction. During image formation, the control portion rotates the motor in the first rotation direction, and when a replacement mode is set in which the development unit is demounted from the apparatus main body so as to be replaced, the control portion rotates the motor in the second rotation direction so that the developer bearing member is rotated by a predetermined amount in a direction reverse to a direction in which the developer bearing member is rotated during the image formation.
