    摘要： A developing roller on a circumferential surface of which toner is held includes a plurality of first grooves formed in parallel to each other at approximately equal intervals, each in a direction inclined to a circumferential direction of the circumferential surface of the developing roller; a plurality of second grooves formed in parallel to each other at approximately equal intervals, each in a direction inclined to the circumferential direction of the circumferential surface of the developing roller, each second groove intersecting each first groove, the first groove and the second groove each having a U-shaped cross section; and a protrusion portion disposed in an area surrounded by the first groove and the second groove. In the developing roller, the protrusion portion has on a top surface thereof a plurality of minute projections, and when a surface roughness Rz of the top surface is RO, RO is 0.5 to 2 times an average grain size of a particle of the toner; when a distance from an average line of a roughness curve of the surface roughness RO to a deepest part of the first groove is D1 and a distance from the average line of the roughness curve of the surface roughness RO to a deepest part of the second groove is D2, each of D1 and D2 is 0.5 to 2 times the average grain size of the particle of the toner; and a relationship of the RO

    摘要： An image forming apparatus includes: an image bearing body that is rotatable about a central axis thereof, and that bears a dot-like latent image, on a surface of the image bearing body, in each of a plurality of divided regions that are arranged in rows along a direction that intersects an axial direction of the central axis at a predetermined intersection angle; and a developer bearing roller that is rotatable in order to make visible, as a developer image, the dot-like latent images borne by the image bearing body, using a developer borne on a surface of the developer bearing roller, the developer bearing roller opposing the image bearing body such that an axial direction of the developer bearing roller is parallel to the axial direction of the image bearing body, and that includes a helical groove portion on the surface of the developer bearing roller, the helical groove portion being inclined at a predetermined inclination angle with respect to the axial direction of the developer bearing roller and being formed having a uniform pitch in the axial direction, wherein a value that is a tangent of the inclination angle divided by a ratio of a moving speed of the surface of the developer bearing roller to a moving speed of the surface of the image bearing body is different from a tangent of the intersection angle.

    摘要： Every other input pulse is extracted from an input signal containing alternate phase-advanced and phase-delayed pulses read out of a magnetic disk unit, a magnetic tape unit or the like. Output pulses in synchronism with the pulses thus extracted are produced. This extraction may be effected only during a predetermined length of time after staring application of the input pulses at the time of pull-in of a phase sync circuit. Whether phase synchronization is to be effected in accordance with advanced-phase or delayed-phase input pulses is determined from time to time as required.
