摘要： PROBLEM TO BE SOLVED: To provide a developer carrier whose developer carrying performance is not greatly degraded at an initial stage of accumulation of image formation and which can achieve stable developing performance over a long term. SOLUTION: A developing sleeve (developer carrier) 21 is provided in a developing device, and magnetically carries developer having at least toner and magnetic carrier on its surface to thereby develop a latent image formed on a photoreceptor drum. The surface of a developing area 21a of the developing sleeve 21 is subjected to blast treatment so that a recess having a larger radius of curvature than an average particle diameter of the magnetic carrier may be partially formed at 10% or more and 80% or less per unit area.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of fogging in a white portion increased at the setting of an image forming mode, in which the circumferential speed of a photoreceptor drum is made low. SOLUTION: In a plain paper mode, the circumferential speed of the photoreceptor drum is 160 mm/sec, the circumferential speed of a developing sleeve is 240 mm/sec, and the ratio of the circumferential speed of both of them is 1.5. In an OHT mode or the like, when the circumferential speed of the photoreceptor drum is set to 1/2, that is, 80 mm/sec, the ratio of the circumferential speed is set to 3 and is doubled, by using 2 being the invert of 1/2, and further it is set to 2.1 to 3.9, which is ±30% of 3. Thus, the ratio of the circumferential speed of the developing sleeve to the photoreceptor drum is made larger than that in the ordinary image forming mode, and the fogging in the white portion is maintained at an equal level to that in the plain paper mode.

摘要： PROBLEM TO BE SOLVED: To prevent a toner existence judgment from being erroneously detected and suppress an image density from lowering in an image forming device which judges the existence of toner remaining in a toner storage part by a patch detection method. SOLUTION: The image forming device is provided with a 1st toner supply control means for controlling the driving time of a toner supply part on the basis of the video counting number of density signals of image information signals and a 2nd toner supply control means for correcting the driving time of the toner supply part which is determined by the 1st toner supply control means and constituted so as to judge the existence of toner remaining in the toner storage part on the basis of a density signal of a reference toner image. When the density signal of the reference toner image is a prescribed value or less, the driving time of the toner supply part which is to be additionally corrected per image by the 2nd toner supply control means is set longer than a case that the density signal of the reference toner image is larger than the prescribed time.
