    摘要: A thermal printer that forms an image on a sheet. The thermal printer includes a thermal head having a plurality of linearly arranged thermal elements, a device for converting image information into bit-map image data, and a device for storing the bit-map image data. A predetermined portion of the stored bit-map image data is transmitted to the thermal head, and a remaining amount of the stored bit-map image data which has not been transmitted to the thermal head is detected. A time interval between a transmission of the predetermined portion of the stored bit-map image data and a subsequent transmission of the predetermined portion of the stored bit-map image data is set, in response to the detected remaining amount of the stored bit-map image data.

    摘要: In an image forming apparatus, a developing device is disposed adjacent to a belt-like photosensitive member. A rotary type developing device has a hollow cylindrical casing rotatable around a shaft having a central portion for rotation. The developing device includes a casing which is rotated in a predetermined direction, and four partitions which divide the casing to make four developing units which extend radially outward from the shaft. A toner storing section or hopper is provided on one side of the developing device, i.e., on a front side of the image forming apparatus, and a toner cartridge is detachable from a top of the hopper, and the toner cartridge is exchanged when an end signal of the toner is detected by a sensor in the casing. The toner hopper is filled by new toner from the toner cartridge, and the toner is carried by conveyor members, which control an amount of the toner in the casing, and a supply roller supplies the toner to a developing roller. Therefore, the device supplies a required amount of toner to a toner supply roller and a developing roller at all times. This provides an image forming apparatus with a great freedom of layout which needs a minimum sectional space relative to a photoconductive element and which, therefore, has a miniature configuration. Also, if amounts of transport of first and second conveyor members are adequately selected, a uniform developer distribution in a longitudinal direction without resorting to a complicated control is insured.

    摘要: A joint having an OLDHAM state coupling at a leading edge thereof is held movably in a direction which is parallel to a joint axis at a full-color printer body. A coupling gear is substantially connected to a developing roller disposed in each mono-color developing unit, which makes up a revolving type developing device. At the time of developing by one of the mono-color developing units, the joint is capable of moving in parallel to the axis of the joint in the state of being rotated toward the coupling. A projection is further provided at the leading edge of the coupling, and a claw is further provided at the end of the coupling gear. Thereby, smooth engagement between the coupling gear and the coupling is made by the help of the OLDHAM state coupling, the projection and the claw. As a result, the driving force is transmitted from the joint to the developing roller disposed in the developing unit, so that the developing roller can rotate at a predetermined speed and direction.
